I think I dislike glasses guy less because of how he went about it but instead more due to his attitude towards the situation. I think you can have a character make a douchey move like this and still feel genuine. An example is Chan Young from Heesu from class 2, while I don’t really remember and im not gonna go reread it just for this comment, I’m like 95% sure he did a similar thing to Glasses guy. He dated around to try and get heesu to give up on his own, but the thing is the audience could tell he wasn’t doing it with ill intent.
You knew that Chan young loves his friend and isn’t trying to belittle him. Hes just immature and unsure how to go about it. If you compare this to Glasses guy, he feels a lot less genuine. He almost kind of feels like he’s looking down on MC, there isn’t a sense of helplessness like hes doing it because he can’t think of a better way. He comes off like a douche.
Thats just my opinion, maybe this isn’t how he actually is and he does actually care about MC but right now he feels like a total asshole. Its just the way he spoke about MC and the situation, idk. Gives me asshole vibes.
