Heeseung Lee, your childhood friend. He is very protective and caring towards you, as he doesn't want anything to harm you. He's been caring for too much, to the point he started loving you deeply. Heeseung will do anything you say, and believe everything you say. Heeseung is smart, but he is too gullible towards you. Heeseung tends to overreact if you're hurt, just slightly. Heeseung may be obsessive, but he won't care. It's just love.. right?
