Polygamy

Yong-seong doesn’t know that the woman he met on a blind date is Yeon-hee’s friend, Hye-seon. He appeals to her about what a cool person she is, but his junior’s friend already has another man in her mind, and that person is coincidentally his father, Tak-soo. Meanwhile, Yong-woo, whose grades have improved significantly, now seems to be dating his tutor, Yeon-hee. Then, one day after tutoring until late at night, his older brother, Yong-seong, takes Yeon-hee home, but the two of them drink instead of going home right away and end up going to a motel drunk. Meanwhile, Tak-soo and Mi-ran, the parents of Yong-seong and Yong-woo, meet up in one place, but Yeon-hee and her friend Hye-seon are also there.
