Shadow under the moon

Doyeong, a student retaking the college entrance exam, is looking for a tutor to help him gain admission to Korea University. Through a high school friend’s introduction, Doyeong arranges for tutoring sessions with his former class president. However, his tutor turns out to be Hajin, the former class president from the first semester who disliked Doyeong. Throughout the session, Doyeong can’t properly concentrate, constantly distracted by Hajin. Seeing this, Hajin suggests canceling the tutoring arrangement. “If I mess up again, you can punish me however you want, with a whip or a rope!” Unable to give up the tutoring, Doyeong blurts out this desperate phrase, causing the atmosphere of their sessions to completely shift into a very different direction.
