A model student makes friends for the first time. Their friendship grows while confronting school violence.


Si-eun has no interest other than studying. When someone provokes him, he does not shy away from the fight that comes in his way. He has been smartly protecting himself by making quick decisions and made good use of his surroundings. However, he is in danger, and he gets help from Soo-ho and Bum-seok. A great friendship slowly emerges among the three of them while they try to survive in a school where bullying always happens. The ways Si-eun, Soo-ho, and Bum-seok deal with people and violence show how the feeble teenagers become strong.
