One day, Kang Joo-han, the president of the Hakcheon sect, receives a disgusting package. Inside the box is a rope that is worn out and broken. Thinking that he might be one of the perverts who have always been interested in him, Joo-han goes to the sender written on the delivery box to retaliate. In an abandoned factory in a deserted corner, a man attacks Joo-han from behind, Seo Jung-woo. Jungwoo wraps a rope around Joohan's neck and tightens it. Joohan feels strange in a situation where he is being strangled. Jungwoo notices Joohan's erection and lets out a ridiculous laugh. Unlike Joo-han, who thinks it's just a physiological phenomenon, Jung-woo realizes how to make Kang Joo-han, who has a lot of pride, miserable. Kang Joo-han has forced sex with Jung-woo. He swears and rejects Jungwoo, but on the other hand, he is overwhelmed by the pleasure he feels for the first time.
