Bottom-Leaning, Usable: Continuously Updated
Lots of spoilers. These are my reactions that I sent to a friend while reading. Hate beautiful weaklings, female rivals, dead flower-vase characters, and pretentious, foul-mouthed characters. If there's a white moonlight, it's called a yandere but is really just mentally ill. Steals the love interest and hogs all the spotlight, while constantly being glorified.

No book is perfect, but every book here has something irreplaceable to offer, whether it’s the plot, characters, or ideas. A place to return to when I run out of things to read

Novels set in the war years always have too many last resorts. We cannot blame anyone in this situation harshly. Even if we have God's perspective, we cannot make the best solution in the worldly sense, and those who have experienced it personally are even more helpless. Whether Antemon loves Allen or not is an eternal question. I think two people must be in love. This kind of love is not only the sympathy between two geniuses, but also the little things in their daily relationship. But the love between two people is both vast and small. It's so vast that no one else can fit into their lives; it's so small that it can be given up without hesitation in overall choices. In the meat grinder of war, no matter how strong individual emotions are, they are nothing but a speck of ashes in history. The starting point of Andemon's love for Allen was Allen's unremitting pursuit, which allowed him to see Allen's indomitable quality. For a person who has been immersed in the intelligence world for too long, it is a fatal attraction. But it was precisely because of Allen's persistence and unwillingness to seek perfection in life that the tenacity with which Andemon fell in love became the source of his loss of Allen. In the end, Allen would rather leave his life in the gray tower than live with a broken memory. This is the life creed that Allen insists on, and it is also what Andemon first fell in love with. This is an almost cruel fate. Allen loves Andemon because of Andemon's unique temperament tempered by years of intelligence life - calm, profound, and in control of everything. But these qualities he loves are due to Andemon's instinct to put the interests of the country at the highest level. Like two sides of a coin, the person Allen loves is destined not to put him at the top. "Love and Hate Come from the Same Origin" is Allen's most realistic portrayal of Andemon. Allen's love and hatred for him both stem from one thing - the essence of an intelligence officer that makes Andemon charming and cruel. I always read online that some people feel that the HE ending of this book is not as good as BE. I think the ending is the climax of the book. If the story stopped at the Gray Tower, it would be just a tragic story; when the dust settles, when Andemon finds Allen who has lost his memory again, will he feel uneasy conscience and sleepless nights when facing his lover's face? The guilt for his lover tortured him, and the disappearing black notebook was like a sword of Damocles hanging over his head, and he didn't know when it would fall. Therefore, when he saw the notebook, he was first excited and then felt almost despairingly calm. The contents of that black notebook have always been talked about by us. I have read many fanfics, and most of them write about Allen discovering the contents of the notebook, and ultimately committing suicide to end this painful and deceived life. I think it doesn't matter whether there is anything in the notebook or not, the key is Alan. After so many years, is he still the same young man who would rather suffer than be numb? After so many years, will he choose to stay together, or has he learned to compromise? We have no way of knowing these. The author leaves the final outcome to Allen, letting him decide his own life, allowing him to truly choose his own destiny, and not be coerced by the tide of the times or Andemon's will. Everyone who participates in the war cannot escape from the war. Even though the war has ended long ago, the haze of war has never gone away. Allen is being monitored and is not allowed to go far; Andemon still lives in the cage he built, trapping himself and Allen. Those broken memories in the gray tower, those loves broken in the war, those helpless in the face of fate - they all sank to the bottom of history, forgotten and buried together with this love that burned to ashes.
I may think differently Even if the national interest is above all else, can't he be freed after everything? Right now, Allen can't see his mother, and he doesn't even know that his mother is Mrs. Custer. Allen can't shine in his favorite fields of cryptography and mathematics. He has lost his memory and wandered around London. He has lost his good friends and has nothing. But now that Andermon is successful, he still wants to tie up Allen? If my memory is correct, he told others "My lover is dead". Did he regard the current Allen as the substitute of the former Allen? You clearly love the old Allen, why did you lie to yourself? Isn't Ellen suffering enough? Isn't it painful to forget everything, even your own parents? He has dedicated so much to this country, why did he end up like this?
I watched it a few years ago. Recently, there was a war between Iran, Israel and the United States. I thought of "Gray Tower Notes". War is a game played by politicians, but it is a group of patriotic children who are sacrificed. Who was not sacrificed in "Gray Tower Notes", Alan, Andermund, Alan's mother, or everyone in the group portrait at the end (I really like this group portrait). I will not criticize who is right or wrong, and I am not qualified to forgive anyone. There are only 26 days of world peace. When will the 27th and 28th days come... How far does the bullet have to fly to turn into a white dove?
I have admired him for a long time, now I finally see him Early morning of November 1, 2025 The first thing I knew about this book was the most famous line, "Dear, have you seen the gray watchtower outside? The moment I saw it, I suddenly felt that I no longer love you." Before reading this article, I thought it was be. After reading it, I found that it is actually a bit like oe's he. The full text is from Allen's first point of view. Just like the name "Gray Tower Notes", it is a note written by Allen during the period when he was imprisoned on the top of the Gray Watchtower. Because it is Allen's first point of view, it is even more difficult to pry into the contribution of the other protagonist in their relationship. We can only understand Andermon's efforts from a few words. However, after reading the full text and thinking rationally, I still can't help but feel that Andermon is the source of most of Allen's painful memories. Undermon is too rational and loves his country too much, so on the premise that he loves Allen deeply, he will still use Allen to put Allen in danger. Allen died in repeated deceptions and despair, but was reborn in the love of Andemon. Some time ago, there was a popular type of cp, idealists and realists One person embraces ideals, has a pure heart, and is full of enthusiasm, but is often hit hard by the wall of reality. One, clarify the rules of reality, be clear-headed and calm Idealists envy realists for their clear understanding of world affairs and their ability to avoid being hit by reality; realists yearn for the enthusiasm and innocence of idealists. Allen and Andemon are exactly like these two. Allen is naive, enthusiastic, and has his own most authentic understanding and persistence of things. He loves his country, so he will still be passionate when Andermund tells him that the country does not trust him, and help solve the "mystery" behind Linton's back; He loved his mother, so after he learned that her mother did not die in the "accident" when he was young, but helped the Nazis invent the "mystery", he still firmly believed that Jane did not treason. Allen didn't understand why Jane helped the Nazis to defend a leader who was anti-human rights, but he still firmly believed that Jane did not treason, she just changed her allegiance. I've talked too much about Allen (I can't help it, these are Allen's notes, I can't mention him less), let's talk about Andermon. Undermon is a typical realist. He loves Allen, but he is the boss of the Intelligence Agency. He has things he must do, so he will deceive Allen and use Allen as bait to achieve his own goals. He pities Allen's childish nature, but he also hates his childish nature. He pityed his mathematical genius and his talent in cryptography, and understood that he wanted to use his talent to show off his skills in this unprecedented cryptographic war. At the same time, he also hated him for putting himself in danger regardless of the consequences; he also hated him for never looking forward or backward in the choices he gave him, and only doing what he wanted. The story of the two people has a tragic color embedded in their respective characters. In fact, as Allen himself said, there was nothing wrong with them, they just shouldn't have fallen in love in this war era. Before the idealistic eagle can truly spread its wings, it is imprisoned in the tower of reality. Genius is hard to find, ambition is hard to achieve The young eagle with broken wings hides its scars and pretends to forget the pain That blank notebook was a chance for a comeback that Allen gave Andermon, and it was also an exemption for himself. Although emotionally I still feel that dying in a tower might be better for Allen However, for Allen, who is striving for peace, he may want to see the post-war world more "My dear, I try to forget the past But when I see the gray watchtower, I can't help but recall those despairs. My chest still hurts, but I think you must be in pain too Peace is really good" (Only my personal opinion. If you disagree with my opinion, please do not attack me. A thousand readers have a thousand Hamlets. Rational discussion is welcome) (I like this article very much and have been fascinated by it for a long time) Come here for the fame and return with a full load (Broken Jinjiang, you have to verify before you can comment. I couldn't see the verification code clearly. I vomited and it took several days to send it out.)
Many people say that Endermund killed Allen in the end, and he should not continue to pester Allen. If the ending is really like this, then I will be even more unwilling. Keep entangled, and always be happy. No matter whether the memory is restored or not, a person is worried all his life, and a person is silent about the truth. How can it not be considered love? Love and pain are intertwined. Although there are countless ways to separate each other, I continue to entangle because I love you.
It is worth noting that Allen's experience actually had several foreshadowings. 1. From "almost losing the trust of Whitehall" to narrowly escaping from the isolation review, Andermont relied on "selling himself out", personally investigating the underworld, and personally disposing of his fiancée to regain trust. When inviting Allen, C mentioned that his parents completely lost trust because of a letter from an enemy friend. The Eagle Incident is the recycling of two foreshadowings. The person in charge had been exposed before arriving in London, but once his identity was made public afterwards, Allen exploded. The two have been friends for many years and have extensive correspondence records. Allen is the head of Office No. 1, So this is a dead end anyway. Allen must "get involved personally" in advance, "actively" participate in the Intelligence JV's Falcon Project, personally "dispose" of his old friend before the review mechanism is activated, and fulfill his obligation of "British interests above all else." Therefore, Andermon, who was in charge of the operation, had to insist afterwards that the young eagle was dead and that Allen could finally return to Plimpton. 2. The task of developing the MI machine was first handed over by the Prime Minister to C, who then handed it over to Allen, bypassing Andermon. After the task was completed, it was the Prime Minister who finally signed Allen's opinion on how to deal with it. After the war, the machine was destroyed to keep it secret. Of the three developers who knew about it, one was probably inseparable from the situation all his life, one had his memory deleted, and the other was a greasy cable factory worker (Raphael was mysophobic). A 3. Allen and Andermont are the comparison of C and Jane back then. The gray tower is the only variable. In order to prevent the news that "Mystery" had been deciphered from leaking out, JV abandoned the entire city of Coventry for this purpose, but until the end, they did not deal with Allen, who controlled the heart of "Mystery" but was inextricably linked to NC. Allen finally survived, but he couldn't leave with the memory of "mystery". In front is Andermon's bottom line, and behind is the bottom line of the senior management. If one party breaks it, the agreement will be invalid. In the end, if Allen successfully escapes from the Gray Tower, Whitehall will have reason to intervene. After all, they are originally afraid that Allen, who has regained his freedom, will run abroad like his mother. 4. When introducing the code name Z earlier, Arnold said that he would brainwash people who had to leave and who really had too much information. In other words, even if Allen does not enter the Gray Tower, he will probably have to get such an injection if he works like this until the end of the war. Therefore, Raphael did not "return to his previous life" as Andermon said. The memory-erasing drug was stolen from the German JZ camp, but their senior officials did not believe in the efficacy of the drug and demanded that Young Eagle must come and deal with Allen in person. Arnold also hinted that "they are still in your brain and have not been lost." The real drug was probably not LSD. It was the person who made Allen finally decide to throw away the recoverable notes.
I finished watching it in mid-May 2023. Every time I look back, after seeing the plot before being imprisoned in the black tower in the later stage, I will start to feel uncomfortable, cry, and feel sorry for Allen. . [Split] Allen made his choice then. He has lost too much, even if he can only recall happy or painful memories from the past, together with the cryptographic knowledge in his mind, he will be forever imprisoned in the gray tower. In the physical book, Arnold said, "None of us is the winner, and none of us can escape punishment." Andermund's thoughts are too deep, and so is his love. Allen told Andermon that it was not his fault, nor his fault. They were wrong because they should not have met in this war era. Did Andermund ever think that as long as Allen forgets this past and never thinks about it again, thinking that they met in a peaceful time, they will have a different ending, and feel that they will be happy until the end of their lives. Even if only he can remember the memories of their relationship before the war, it doesn't matter. It's just that there may be a sudden sting in the heart at a certain moment, and it feels uncomfortable for a while. It's nothing, nothing. He gave what he thought was happiness to Allen. Will he think of the flamboyant young man under the apple tree outside the Cambridge Library at a certain moment when Allen smiled at him? Will he regret making such a decision at some point? I don't know. He made a mistake, and now he has asked for enough. He hopes that Allen will live and stay with him happily and carefree. I can't help but think about it, my understanding is as above. This feeling is really complicated for me.
I don't quite remember when I first read this children's book, not to mention ten years, but six or seven years ago. I was still young at that time, so I don't know where I picked up this book, and on which little website (Biquge or something else, I didn't know about Jinjiang at that time, so I just randomly searched for books to read, and I just read whatever I saw was good, and I didn't care about anything else, as long as it was attractive enough. The author even found out that the ending was not satisfactory after reading it) In my mind, this should be the first online work I have read from a first-person perspective other than literary works (because I have never liked reading first-person stories, and even if I have read them so far, I have not seen many third-person stories). The author remembers that my strong interest in cryptography started from this book. I wonder if other people have had similar experiences. This is because the book is a very good book with relevant and informative content, and it tells interesting things that may not be exposed to much, or may sound boring. Yes, I don't mean that it's interesting, I just mean that the feeling suddenly appeared, and the hobbies related to it naturally emerged, as well as the method to learn more about it. For example, I read a book related to finance some time ago. The author, who had never been interested in this aspect, started to pay attention to the financial circle... And plunged into the stock market... I won't mention this. Continuing to talk about this book, the reason why the author particularly liked it at the time was that its unique writing style and selected themes were rare—— "He misses the clear blue sky in Cambridge, and the lover who bent his eyes and smiled under the apple tree outside the library..." (Attached is a sentence that he has always remembered clearly.) It was basically difficult to find a replacement at that time (when I first finished reading it, it was hard to let go, and I didn't want to read it again. I searched frantically for similar ones, but there were none, or the author couldn't find them myself. I don't know if they exist now, and I haven't searched for them much since.) I'm not sure if the memories gave it a charm, so that I was still thinking about it long after reading it, but because I was busy with studies at that time, I didn't have time to put it away and then taste it. There is also Yeats's poem "When You Get Old" that appears in the article. I didn't know Yeats at that time, but I just thought the English-translated sentences in the appendix of the article were beautiful. The most unforgettable thing is actually the profound background of the story and the complicated emotions in the article (if I had said it a few years ago, I would definitely have talked about it, but now it's not impossible to say it, but it is definitely not as fresh in my memory as before)... Well, actually I only remember the feeling it gave me after reading it for the first time. It was very heavy, like dragging in a quagmire. You have no way to evaluate whether what someone did is right or wrong. You cannot look at the people in the article as if they were a frivolous thing, nor can you just use a few adjectives to summarize their personality. It is inconvenient to define, and of course it is inconvenient to comment on them, leaving it to other subsequent readers to look at them. The author originally thought that I could always remember this book and was deeply impressed, but I suddenly opened it today and wanted to say something, but suddenly found that I had forgotten many things. When I was writing, I remembered some of the feelings I had when I read it for the first time, including the sudden sadness I felt after reading it for the first time. But there are still some things that I can't remember clearly. I am leaving a comment today because I am afraid that my impression will become less and less clear in the future, so I will talk about what I can remember so that I can come back and read it later: Oh, it turns out that I have thought about it this way. As for why the first time is always mentioned in the above content, it is because it brought the deepest feeling to the author for the first time. Even if I bought the physical book and read it again after a few years, I may still vaguely remember the plot and not have as deep feelings as the first time, or maybe the memory is beautifying the book. Speaking of physical books, I also have an interesting memory. I just bought it and even though I didn't want to read it, I took it to a classmate from school to read (the classmate also reads all types of books, but he doesn't like to read the ending where the yin and yang are separated) and told him that everyone is alive in the ending. After reading it, he looked heavy for a while and became unhappy. (To finger) I suddenly opened this book before going to bed. I scanned the title: Oh, this book, but I couldn't remember the content, so I suddenly became energetic and wanted to write something. Unfortunately, it was a bit too late, so I wrote in a fragmented way. I just wrote whatever came to my mind without organizing the logic. After I finished writing, I read it over several times. I felt that it was not very good, and I didn't want to change it. It was not anything serious at all. I'll think of the rest later. 2026.8.2 Stay Time flies so fast in the blink of an eye.
In my mind, foreign bl texts with translated accents are of the highest quality. I've read a lot of comments saying that this is sadistic, it's so sadistic, don't try it easily, ha, I don't believe in this evil. I felt it was okay when I read the first half, but then the truth was slowly revealed later. It was nothing when I read it, but it became more and more uncomfortable as I read it??? Oh my god, it was a dull pain, the kind that stopped my breathing. I didn't feel anything at the time. , I also watched Fu Hang's talk show, I laughed so hard that my stomach hurt, and then I finished reading the next two chapters. It made my heart twitch and my breathing hurt,??, I was overjoyed and sad, I felt like I was out of my body, and I had a headache. Sure enough, the eyes of the people were sharp. This is so heartbreaking. I really don't dare to watch it a second time. "Dear, I saw Is there a gray watchtower outside? The moment I saw it, I suddenly felt that I no longer loved you. "The more I taste, the more my heart aches. This is an authority I dare not challenge???" Allen's initial family background was like imitating Harry Potter. Both his parents were dead and he stayed at his uncle's house. He didn't go to school at first and he was forbidden to learn mathematics (forbidden to travel to the wizarding world). Only after reading jj's comments did he realize that the prototype was Turing. The music and books appearing in the novel always reveal the author's profound knowledge. In the two endings, Andemon died, died in the power struggle, and Allen lived alone: Allen and Andemon still lived together and loved each other, but Allen had read the notes. In order to protect Allen, Andemon prevented him from accessing the password and Plimpton Manor. In order to keep this love alive, Allen pretended that the notes were blank. What is a bond? Or shackles? While watching, I always wondered whether Andemon liked Allen or not. Maybe because of his pure love for novels and his habit of pure, flawless and vigorous love, but with a bit of real struggle, this love seemed impure. Allen was eating in the restaurant and went through the back door. It was Andemon who prompted him. Later, he confronted Lina. Andemon went to rescue him alone. He loved Allen, but he used him again and again. It was a dilemma. I felt that it would be better if there was Andemon's perspective to show the cutoff in his heart. It would be more sad... Allen was also caught between love and non-love, choosing back and forth. In the end, he got tired of love. But after losing his memory, after reading the notes, he still chose love. This kind of dilemma arrangement can be called a writer! Empty Dengliuyuan is a writer! !
When a story is about to end, we always think of its beginning - pre-war London was still prosperous, people lingered in theaters and bars, and the prices of brandy and wine did not reach the high prices of 1940. Cambridge, which is only 90 miles away from London, is like a paradise on earth in my memory.
