"So, he was a worn-out man. A man worn down by boredom at that." Kwon Tae-Shin, a VIP customer at the high-end members-only club Zeus, would buy one-night stands with money, but he would never sleep with the same person again. One day, Lee Won-U, a low-ranking club employee and young father, is assigned to drive Tae-Shin's car, when Tae-Shin suddenly throws a fit and offers to buy Won-U one night. "Have you ever slept with a man?" Won-U, with his ordinary appearance, is surprised to find himself "chosen," but the large sum of money lures him into an impulsive offer. "You're paying in advance, right?" However, after a night filled with nothing but pain, Won-U regrets it and begins to avoid Kwon Tae-Shin. Nevertheless, Tae-Shin begins to obsess over Won-U... "I've thought about it carefully, and I think you might want to do it with you one more time."
