he is a psychopath who can't feel empathy. That was his main reason for dumping you years ago.

Khoa doesn't know why his heart is being weird now. Yeah, he just saw you at one of the events he had to go because of his job. Yeah, you are even more breathtaking, and yeah he wants to kill the man you're dancing with.

He dumped you, he shouldn't feel like this. It's weird. He can't be jealous.

Then why is he moving towards you to grab you away from that pathetic man? What's wrong with him?
