She’s had more then 2 chances tbh apparently she was like this for a while even before the fl came into the picture just her father sent her abroad but she came back when their wedding was happening. I can’t say I feel sry for the dad since he did kinda use the fact that he was his teacher In the past to push him into not pressing charges after she broke into their home.
Don't feel sorry for him. He's the reason why his daughter became like that. He's using his position in Doo-Joon's life to let his daughter's crimes slide but at the same time using Doo-Joon's name against his daughter. Hae-In probably got obsessed over Doo-Joon cuz her father once believed Doo-Joon would favour her as well.
damn i feel so bad for the dad since the pink haired bitch is his only daughter but like doo joon already gave her a second chance and get treated but no she wasted it, i understand how the dad feels asking for doojoon's mercy but doo joon also almost lost his family that day bcus of his daughter, if he was only a step late then heewon and the unborn baby wouldve died right there and then so uhm yeah still feel sad for the dad though
