I feel like yeonwoo is making haesol experience feelings she has not felt ever or in a long time since she's always deadpan and that's quite literally making her look crazy/yandere or whatever. She probably has a trauma or something with showing emotion and isn't used to it so when we finally find out why or when she gets over it, she and yeonwoo will be happier. Since, yeonwoo is the one she is taking her feelings out on means she probably cares for him more to even show that side of her. Whew!
