Daejin’s mother, Seo Young, comes up with her brother-in-law, Dae-jin’s friend. I can not refuse to accept the sudden proposal of Seo Young to teach sex to be born as a man. On the other hand, Daejin is very popular among women, unlike the Junjong. However, he has been in love for Yeon-hee, a quasi-type mother for a long time. Daejin, who heard the stereotypical saying that her parents are about to divorce, is now starting an aggressive affection for Yeon-hee.
