Overall, this is a tragedy caused by a book. I stupidly borrowed books for my roommate, but ended up following him for so long... Finally, he came to return the book, and the person bought the book as a gift... After taking the book away for no reason, I found a note of shame... A certain idiot had a desire to have a myocardial infarction...
"I have a name!"
"Well, tail~"
