So I suggested to go with Ruri, who is familiar with fashion.
HAHAHA OF COURSE YOU DID, is this satire? Am I reading satire right now? There's no way someone can be this stupid, right? Will he invite her when visiting each other's houses too? At this point, I wouldn't be surprised.
Does he even realize that he has a girlfriend? Yeah, just go into a changing room with your childhood friend and stare at her tits while on a date with your girlfriend.
