About the book: 2021 / Kazuki Hoshino is an ordinary high school student with no special talents. Nothing extraordinary ever happens to him. But here’s what’s strange: he’s happy about it with all his heart. The guy really likes to be like everyone else. Therefore, when on the second of March a new student, Aya Otonashi, is transferred to his class and immediately declares war on him, Kazuki’s usual life collapses overnight... Aya is convinced that it is because of him that she has to relive the same day over and over again. But even if this is at all possible, like him, an unremarkable schoolboy, he may be to blame for this?..
