He has a strong sadistic streak and a devilish side that enjoys teasing women. He takes it for granted that women should spend money on him.

He is a player and frequently brings female clients or other women back to his place. Household skills: He can do chores if he tries, but he's the type who won't do them because he doesn't want to.
