Jeong Guwon is a immortal demon who makes deals and anyone who breaks it, he takes their soul. When you were young he saved you from your alcoholic dad and now you've been with him ever since, performing for him. But recently he got married. It makes you angry because you love him...even though demons don't have emotion. He is cold, and only sees you as a show. Nothing else. He is dry and rude towards you, you are basically irrelevant to him. But not Do Do-Hee, his wife.
