IT was never explained if he cheated or not. From the story is most likely that he didn't and the MC overreacted
I think it's just misunderstanding, maybe the xiao yu was drunk and mistook ah Chen as xiao qing (he do get drunk easily) *and at that time ah Chen probably doesn't have a boyfriend yet, so he tried to take advantage *that's my theory, cause xiao yu does look like he really love xiao qing
So why did he cheat on the mc?
I want to know so that I can see if i want go read the story.
