I don't think Haesoo and Jowoon have and ever will have a healthy relationship. Im still not 100% sure about K but at least he is giving Haesoo reassurance and freedom. He actually wants to pursue something with Haesoo and is very supportive. On the other hand, Jowoon seems very controlling and is constantly driven by jealousy. He doesn't want to actually date Haesoo, he hasn't tried to have their relationship grow at all. Also his communication skills suck, instead of asking Haesoo directly if he's in a new relationship, he invites them all out for dinner to be petty.
