Se-Rim-ui Cheolchik

Rumors that Han Se-Rim is a gangster have left everyone at school afraid of her. When model student Kang Seung-U is assigned to her through a mentor-mentee program, his perfectionist streak pushes him to get closer so that nothing goes wrong, though he cannot make sense of who she really is. What follows is a charged romance between a girl who lives as though tomorrow may never come and a boy who has already planned out the rest of his life.
