Well the man IS straight. It doesn’t make him homophobic it just means he can’t see guys that way
I know but... it’s not his girlfriend’s fault for turning into a guy all of a sudden.
So? What does him kissing her have to do with that excuse? He’s still being supportive, it’s just that he just couldn’t kiss her - what’s so wrong with that? It’s not like he was rejecting a kiss out of her love either - it was literally just an experiment and it didn’t hurt the girl’s feelings.
He’s kinda overreacting over kissing his girlfriend just because she’s a guy? I’m willing to take Jieun with me and screw that guy.
