Turn Up summary:

One day, Kang, president of the Hakcheon faction, receives an unpleasant package. It's an old broken rope. Thinking it might be a gift from the perverts who usually take an interest in him, he goes to the destination written on the delivery box to strike back. There he finds Jungwoo, another Korean gangster. As Jungwoo wraps a rope around his neck and tightens it, he feels strange. Jung-woo, who has noticed that Kang has started to get hard, spits out an incredulous laugh. Unlike Kang, who thinks it's just a physiological phenomenon, Jung-woo realizes how miserable he can make Kang Joo-han, proud as a cock. Kang Joo-han is then forced to have sex with Jung-woo. He swears at him and rejects him, but on the other hand, he feels pleasure for the first time.
