In the Music Series, the Male Protagonist in the World of Writing Self-help Manual

(Lonely Rock + Mygo Worldview) After traveling to a different world, where the trajectory of development diverges from his original, Chen Xinghua feels his future is bright. He has a sweet childhood sweetheart, Goto Ichiri, who's just a bit socially anxious. He also has the standard cheat code for time travelers, but it's called the Otherworld Male Lead System. His future is bright, if he can handle the sudden appearance of teenage thugs, the increasingly bizarre campus, his childhood sweetheart with a parallel personality, and the increasingly intense gravity of a girl band. So, Chen Xinghua sets a small goal: to avoid being locked up in the basement shared by three bands before graduation.
