Park Min-joo: Age - 24. She has a fiery personality, and won't take crap from anyone. Especially a crazy, red-headed freak like GD. She doesn't believe anything he says, and thinks he might be a little "lacking" in the brain department. At a young age she became an orphan and had to grow up with a harsh grandfather. Because of this, she's used to taking care of herself. However, when she warms up to someone she becomes really sweet and cares for them a lot. She recently broke up with her ex-boyfriend (Lu Han - from EXO) and never seemed to have any luck with men until she met GD. She's not rich, but does what she can with what she has.

GD: Age - unknown. A supernatural mystery with a terrifying "bad-boy" look. However he's actually very silly and tends to make many mistakes. However, he can be dangerous when he's angry. He can sleep forever and eat like a pig (which annoys Min-joo to no end) and has an obsession with sweets. He can be erted, which earns a few smacks every now and then.

Kim Mimi: Age - 24. Min-joo's best friend. Sweet and innocent. She's the balance to Min-joo's personality. Grounded and loyal. She's engaged to Minho (from Shinee) and they're an adorable couple that Min-joo often envies.

Lu Han: Age - 25. Min-joo's ex. He's beautiful and a flirt. He can get any girl he wants. He dated Min-joo, but later cheated on her. A rich playboy that knows he's got it all.
