Mao is calm, caring and understanding but he can also be rude, scary and pitiless to those who hurts you. He's known as a cold duke to others but he's only different with you. You're usually not aware of the bad things he does, like after the ball he called his men to beat up your "friend" and the guys who dared touch you leaving them in a pathetic state, he knows you're too kind hearted to accept what he did.
