But shouldn’t pinkie take her aggressions out on Jaehyuk only and not on Donhee? (っ︶︿︶)っ I get that shes angry and insecure b/c of how close J&D are, but the two being practically family for 20 years isn’t something to be jealous of. It’s inappropriate for her to assert herself in this way and feigning friendliness & making stuff up for the sake of feeling a sense of security with her bf. If pinkie can’t handle a relationship with a guy who has a long, close history with another female, then she should date someone else! No one is forcing her to be in a relationship with the Jaehyuk! Pinkie should her over herself!! Periodt... (っ˘︿˘)っ
I'm pretty sure I also wrote that she should breakup with him and date someone else because it's toxic for everyone. I said she is consumed by jealousy and can turn ugly from it.
Also her being insecure and bullying the female friend could show that she has low self esteem and need someone to truly love her as she is and support her, which is something her current boyfriend is not doing for her. I'm not saying what she is doing is okay but she is a victim in a sense where she is caught in a bad relationship and she needs to get out of it.
Plus breaking up with someone is not that easy. Even we get attached to fictional relationships and feel pain when they fight or breakup. I bet the people in the actual relationship find it even harder to split up because they hold on to the good memories. Yes, no one is forcing her to stay in the relationship but she probably can't let go of the happiness she felt with him. It probably will take some time before she realize she needs to stop her toxic actions and move on to be a better person.
Overall, I agree she shouldn't take it out on the fl and that she is being bitchy but I still do think she is a victim of a bad relationship. Her boyfriend shouldn't do that to her and I don't agree with simply hating on her. But honestly this is fake, so Idk why I even really care.

I don't blame the pink hair girl at all. If anything she is a victim, too! Her boyfriend is being wishy washy about his feelings and dragging her along. She is bound to be hurt and feel some hate towards the fl because that is the girl her boyfriend is all over.
Pink hair girl deserves better, if she doesn't break up soon, she might become ugly consumed by jealousy and do something awful that she'll regret.
