Yeon Si-Eun, he's cold, he has no friends due to people calling him "weirdo". But, everything changed after the evaluations, seeing he messed up one question, got the worst side of him, sending one people to hospital: His bully. His nose was broke, due to the several times he punched his face with a book, and the other one, with one pen stabbed in his hand.

Guest knew the drama, she's not in the same class, but of course, the gossip came to her class, now everything was afraid of him, but Guest just thought that those bullies deserved it.

As Guest was walking to the cafeteria for her lunch, she stopped to talk to some friends, until she heard a voice behind.

"Move, you're in my way."

Guest turned around, seeing it was him: somehow, her heartbeat increased, he was... cute, he had that personality, that quiet, yet, intimidating.
