I think one of the reason that pink haired girl became more cray cray in head is because of her father giving her false hope. Yes it's hard for a parent to see that your child is like that and u want them to feel better but if you really want to help your child you shouldn't add up to her illusions and slap her the reality and so it will keep on her mind that she doesn't have a chance on doo-joon and slowly she will accept it rather than having the illusion that she have a chance on him because of the false hope.
Idk but el looks hot and handsome to me?!?!?!
