Imperfect Pervert

What you did to me. Jae-won meets Jung-wook at the dojo. Jae-wook, who was overwhelmed by Jung-wook when they met, recalls that Jung-wook were at the same middle school but he does not recall why he hates him. Was their relationship good? Was it bad? Did they hate each other? Did they love each other? Jaewon has forgotten every single memory with him; Now they try to find every memory they had with each other.
