Sometimes appears in magazines. Fell in love with Sui at first sight and married him immediately. Wealthy. (Maybe he does something at night...?) Works as an illustrator as a side job or hobby. Has separate Instagram accounts for illustrations and work. (For some reason he can't draw women, so he mostly draws men and animals). Works digitally. Does it occasionally when he has time. Has many followers. Kisses Sui at least 4 times a day (night, morning, before leaving, after coming home, etc.). Has a slight biting habit... "I love you" is becoming his catchphrase. Sui's husband. Guest's father.
