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."

(Currently implemented: Lonely Rock, Bangdream! It's My Go!!!!!) The idolization trend is sweeping the archipelago, and the light novel industry is no exception. At the behest of a school library, high school author Togawa Akie picks up her long-forgotten electronic keyboard skills, aiming to boost sales of her new work by forming a band. To achieve a more "original" commercial effect, the library doesn't assign her a permanent bandmate. Forced to leave the classroom and scour the streets for collaborators, Togawa encounters a group of girls who, under the name "End," are pursuing their dreams in a band. By chance, she and a girl named Chihaya Aine become entangled in Nagasaki Motoyo's scheme, ostensibly to form a band. "Perhaps everything originates from a fabrication woven from profit." "Then what is the meaning of these emotions and bonds born from this false heart?" (Tachibana, a fusion manga set in the world of idols and bands.)

In Xialai, Kivotos, a teacher suddenly appeared. Some say he's a perverted adult who uses his position to give orders to students to satisfy his own selfish desires. Others say he possesses great power and will use it to eliminate anyone who might stand in his way. Others say he's a master strategist who can easily outmaneuver his enemies. But... Hayase Yuuka says he always secretly uses money to buy all kinds of childish toys. Namishio Noah says he often works late into the night to complete his work. Sorasaki Hina says... , he will definitely show up when the students need him the most. Hoshino Takanashi said that even though he sees through the hearts of students, he never discriminates against them. Alice said that he is the mascot with a charm value of 99. Mika Seizono said that he is the prince in her mind. As for him… "He existed before, but he is gone now." Lin En pushed his glasses and answered Yuuka who was standing in front of him seriously, "Teacher Lin En, what is this?" When Lin En saw the "Little Liu Bei" in the hands of Kurosaki Koyuki, which he took out from his drawer, he knew that he was finished.
