One day, Seo-jin, a judo instructor, meets Jae-ha, a former member of the national team, who was invited as a temporary instructor. Unlike Seo-jin, who is sad, he feels awkward with Jae-ha's blunt reaction. He ran into Jae-ha on his way home, and drank with him on impulse... When drunk Seojin opened his eyes, Jae-ha was masturbating by calling his name!
