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.)
