Haiga. He said he hung out with this dude whenever his girlfriend “wouldn’t leave him alone” (which was kinda a sus thing to say imo). One day the guy kissed him out of the blue. Did he reject him? No, he decided to try stuff out with him. Everyone’s going on about what a good person he is and I’m just like, “He got bi-curious and cheated on his girlfriend wtf” lol

That’s a lot of words for cheating. A person is welcome to be confused and experiment. It enters different territory if they are already in a relationship.
If the author wanted it to come off as NOT awful then the full implication should have been addressed and some sort of regret shown. Otherwise I’m here thinking that he is absolutely capable of cheating on his new partner.
So are we gonna talk about how he cheated on his ex? lol
