Some notes: The timeline of this book will be different from the original, of course, it is only to the extent of whether the character is in the first or second year of high school. This book has thoughtfully added another week of plot before Crychic, please enjoy the pleasure of the group explosion. Bugs such as Mutoto being too talkative have been fixed. The following is a serious introduction: In fact, Iruma Hibiki was just an ordinary light novel author at the beginning, but in the relationship of breaking up and getting back together, he was eventually caught in the vortex of the girl in the band. If the god of time travel could favor him again and give him a chance to travel back to the past, he thought that the opportunity to change everything must be that afternoon, the first encounter with Nagasaki Motoyo. So, at the end of each distressed day, he whispered in the girl's ear: "Motoyo, let's break up."

On the app called FreeFriends, he met Saki Kawasaki, a woman short of money due to a family change. On the train, he encountered Kotonoha Katsura, a cowardly girl who was bullied at school. He became a model and met Kirino Kousaka, a girl who loved the anime. From that month on, Yuu Kasugano's youth was no longer normal.

Hua Hong traveled through winter and became the Traveler, the twelfth seat of the Fatui's executive officers. After three years of forbearance, he finally made it to the day of the simulation system's activation. He initially believed this was all a replica, a fake, but when Keqing threw a bracelet in his face and, with a suppressed murderous intent, demanded, "Cancer, being hunted by enemies, running away due to debt? What other excuses do you have?" Seeing the lightning flashing around Keqing, Hua Hong raised his hands and said, "Listen... I'll explain it to you!"

If the world lacked someone, it would be different, but it would still function normally. But if a person gave up on doing certain things and thinking certain thoughts, could they still be considered complete? So troublesome—Yi Sheji, a high school student who sighed all day, had spent sixteen years in peace. Although he had no envy for others and no energy at all, he still burned with the so-called passion of youth without realizing it.
