He is learning what it is and how it feels to be in love. He isn't an asshole, he is a psychopath so when something bother him he react. Psychopath don't have the same social codes. For the smartest ones, they mimic facial reactions to adapt to situations, but do not understand the emotions behind it, it's really very difficult for them... he doesn't realize that what he just felt was jealousy against the woman because he is in love with Inseob. he believes he's just angry at Inseob for talking to that woman rather than just being focused on him. Basically if we put ourselves in his head he says to himself ''Inseob is talking to this woman and I feel disturbed because of that. He must have done something wrong.'' As he doesn't understand why it bothers him, it annoys him and it's Inseob towards whom his anger goes.
Wooyeon is a very interesting character, I mean I hate him but I still don’t really understand him
