When I finished writing the last extra chapter, it was around 12 o'clock last night. I was drinking tea and reading the article. I found that I still had a lot of things I wanted to write and hadn't said yet, but I didn't know where to start or where to finish. This article originally only had a short paragraph at the beginning, but the more I wrote, the more I wanted to write it down, and then it ended in a muddle without an idea or an outline. Who is Kakashi? Genius copy ninja. Who is Itachi? Genius Uchiha. We don't know what they are thinking about, love, hatred, responsibility, I don't know them, so even though I have been Kakashi's fan for many years, I haven't written a single word about them. Because I don't understand, it deviates from the character image, but what I write is what I think, the hearts of Kakashi and Itachi, stubborn, bitter, smiling, and fragile. Ninjas are also human beings, they can be sour, sweet, bitter, and spicy. They don't just talk about their responsibilities and hold back. But if you can't see through it, you can't see through it. I can't understand them, but I long to understand them.
