Da-hyun wants to enjoy a hot meeting by calling a man who goes out of the house while her husband goes out for a while. One day, Hyun-soo's stepfather, Seok-hyun, comes to play with his son, and at home he is alone.
Da-hyeon and Hyeon-soo grew up like sisters without their parents, and still live together even after Da-hyeon got married. Sex isn't good between Da-hyeon and her husband, so when her husband is out, she has an affair with a stranger. One day, Hyeon-soo's step-father, Seok-hyeon, goes to his son's house and sees his son's wife's sister there all by herself.—moviefone
