I can tell that his girlfriend (I won't even mention her name since I hate these types of girls) is only there cause they "look good together". And her method of not being jealous is to manipulate him so that he would choose her and stay with her by making him feel guilty and regretful.
I hate the ML too. He is naive and weak. Poor Soyeon, I just wish she find her happiness.
You are so right.
His girlfriend gives me yandere vibes for some reason
