A young man, Yu, who was fired from his company and kicked out of his house, decided to stay at his brother's couple's house until he found a new job. However, he doesn't have a place for himself even at his brother's couple's house, and every day his brother yells at him, saying, "You're a pathetic man to be a virgin even at the age of 30." Yu, who wants to gain confidence no matter what, asks his sister-in-law, Miho, to take his virginity from him. Miho, who sympathizes with her Yu, forgives her body for a little while, but she is attacked by a numbing pleasure.
