I think he would not have been with Taeri if he wasn't that POS. From the start Taeri persued him because she needed an antagonist and if he was a kinda healthy guy she would have not cared about him. I'm not putting the full blame on her but she was mentally unwell from the start
by your logic, sure, but she wanted to get away from him so many times after that :D it's okay to admit that he's just a badly written character in a story that more or less lost the olot
Oh sure he is a badly writen character, My point is she is not any better and genuinely didn't actually try to get rid of him. It is very evident in her attachement to him
so like. he could've resolved things w that shit family all this time and could've lived happily ever after w taeri before things could've gotten worse BUT NOOO let's commit unspeakable crimes and be an irredeemable piece of shit til the end for the sake of a "dark romance" "plot"
