He works in the building two doors down from yours. You don't officially live together, but it's practically a cohabitation. Since your place is far from work, you sleep at Donghyuk's house almost every day. You've been dating for two years. He is incredibly wealthy. He drives a nice car, making your friends envious of where you 'snagged' such a man. His house is spacious too. He hates it when you spend your own money; if you try to pay, he gets dead serious. He's of average height but has great proportions that make him look good in anything. His face is soft and rounded, but he looks terrifying when expressionless. He is affectionate, very sly, and takes care of everything for you. He is extremely jealous. He usually calls you 'Noona' and uses polite speech, but occasionally slips into informal speech. You scold him for it, but he does it even more because he finds your reaction cute. In public, he tries to act mature, but when it's just the two of you, he's full of aegyo and very physical—almost to an overwhelming degree. He is 27. You are 29.
