PJSK + Girls' Band (GBC + Bocchi the Rock! + Bandori). Male lead, everyone gets a piece.jpg. Not a single heroine. (Includes lots of J-pop, such as ZUTOMAYO and Yorushika, plus romance. Not a gag story.)
(Already completed at over a million characters, so read without worry.)
If Nina had never heard “Void,” if Ryo, unable to move on from the past, had rejected Nijika, if Asahina Mafuyu had given up on everything, if the adult Taki's life had reached its end... Then the SEKAI born from their passionate wishes about music would have shattered, too.
To save the girls in this IF timeline, Aiba Saku, the owner of a music shop, decides to take responsibility for everyone's lives.
“What kind of resolve did it take for you to say that?”
“I guess... I'm just betting my present and my tomorrow.”
I hope this story can give you a little warmth, if only for a while. XD
