I think shes great... Nice play.   Tho, it just might mean he finds a new idol /shrugs. But the MC is an idiot,  he wont.
But seriously, the MC is delusional ?  Hes so convince a "pretty girl" wouldnt bang a guy? what a looser...  ok people in the comments. If a pretty girl, a idol that that, asked you to be her boyfriend and to bang her ? would you say no ?  See my point.   This idiot MC reminds me of those people on Twitch, who freak out when they find their favourit twitch streamer has a boyfriend.  They loose their shit to something that should be obvious.
