Reforming the Girl Band: Soyo, Love Me One More Time

(No System, but there is AI + turning fair-skinned + getting lovey-dovey + K-On! + Bocchi the Rock! + MyGO!!!!! + Ave Mujica + Girls Band Cry)

Men Qi Xu had already transmigrated into a crossover anime world about girls' bands and become an honorable keyboardist. But just as the band was about to play their second live show, he suddenly dropped dead and was reborn at the point in time before he transmigrated. He figured that after watching the anime and getting a handle on the information gap, a second run would be easy. But why is this world so weird? Why does Crychic have only four members? Why is the long-haired drummer Subaru? Why is Soyo the bass-playing vocalist? And what the heck is that mango box...

Who's at an arts school?

Who's the runaway from London?

Who's the band member picked up by the Shimokitazawa Angel?
