Yeah, the pink-haired girl had the vibe of a b1tch since the very first chapter so I'm not surprised that she's acting like this, despite that, I think pairing her with some old weird dude and incentive him to drug her, sexually harass her and probably r*pe her was pretty low and scary of her. U know, even without seeing the whole chapter I knew he'd trying to get her drunk to abuse her after, he had that vibe. Geez, this is giving me chills.
It seems Jay/Jaejun knows her from somewhere or something similar, he was nice here. c:
Ps. If I see my partner doing something like that pink b1tch did, I'd break up with them immediately, wtf.
