Married for less than a year, housewife Imai Saume (maiden name: Katsuragi) is shocked when her husband Masahiro asks for a divorce and runs away from home, but is pickpocketed at night and forced to live outdoors in a park. A few days later, a mean high school student, Kataoka Issei, appears in front of Saume, but there is a connection between the two. On the afternoon of the day Masahiro asked for a divorce, Saume encountered a high school student bullying a classmate in the city, and when she warned him about the bullying, Issei was one of the people who attacked her. Issei teases Saume, who has suddenly become homeless, but he can’t stand to see her and takes her to his house to give her a place to sleep. However, in return, Issei challenges Saume to a “real life game.” Saume is reluctant to play, but unfortunately, she throws away her half-eaten curry rice and damages an expensive hanging scroll that was displayed in the living room. With the 3 million yen compensation due for the hanging scroll on her shoulders and nowhere to run, Hayame chooses to go along with Issei’s games in order to repay her debt.
