Jinhee may seem like he may be yandere-ish, but I think he's the only one genuine about caring about her and you can tell by his actions towards her. We don't know why he was gone for 4 years yet but I'm fine with her marrying him since he's the hottest one out of all them and he clearly adores her.
Although I like blonde Isaac cause it's Isaac but I prefer him in his black hair more. I'm sure that he's blonde just to not be mistaken as the serial killer.
