“How many times did you screw me, Sir?!” Min Jae-joon, a urologist who dislikes gangsters but has a thing for well-endowed men, meets Kite, a gangster with a impressive package, while covering for his senior at the hospital. Consumed by desire, Jae-joon secretly hooks up with Kite, planning to keep it a one-time thing. However, instead of keeping it under wraps, he leaves a note, which leads to Kite catching up with him. Expecting a beating, Jae-joon is surprised when Kite asks, “How many times did you screw me?” Jae-joon replies, “Ten times.” Kite demands he pay back tenfold. But instead of the expected beating, Kite proposes a ruthless deal: for each time Jae-joon pays his “debt,” he’ll reduce the count by one. Jae-joon is now trapped, forced to repay the debt to the merciless gangster, who demands an eye for an eye, a tooth for a tooth.
