wait- isn't he that eunwoo nam that haena showed her last chapter..... but also haena's friends & classmates are... how and why would they laugh at her like that.. that's so shitty
I still have hope, the cover is gay as hell. Maybe he falls in love with her and will confess but then she'll realize she shouldn't been with Haena all along, that's how a lot of these work anyway
I dunno, it depends. Interactions between friends are largely dependent on the personality of each person. Sometimes, close friends constantly insult each other while other close friends will keep a respectful distance. If the person in question was Sora and everybody was ganging up on her, that would be toxic. On the other hand, Haena seems to not only be fine with it, but also thrives on such attention.
In this case, I think this is a fairly healthy relationship. Haena's lack of brains is not only well known, but Haena also doesn't consider that a inappropriate topic to rib her about.
