Cheonho thought he was delivering righteous justice when he forced himself on Shin Jehui, the man suspected of assaulting his sister. But when the truth comes out, Cheonho realizes he has committed an irreversible crime against an innocent man. Bracing for arrest or violent retaliation, he visits Jehui to apologize. But Jehui's reaction defies all logic. Rather than demanding retribution or turning him in, Jehui eagerly chases after Cheonho, insisting they start dating. Trapped by his own guilt, Cheonho has no idea how to handle his deeply unhinged victim.
