Park Joon-yeong lives in a room styled with collages of women's faces and photos cut out of magazines. While walking around the neighborhood and taking pictures, Jun-yeong accidentally encounters Da-hye, a married woman. Joon-yeong is hooked on Da-hye as soon as he saw her for the first time. One day, Jun-yeong sees Da-hye with her husband Yoon Seong-gyoo and sees a shocking scene.

New couple Na-ni and Joon-seo left the stuffy Seoul to try and start a cafe in the countryside. Behind the couple's attempt to change, they had some unspeakable worries, so they were sexless people who used their own rooms because they were not sexually compatible. Regardless of her husband's efforts to establish a relationship, her wife Na-ni has long been on an extramarital affair with her sex partner Dal-ho, who has been embroiled in a hit-and-run accident that she never thought of enjoying sex outdoors and is asked for a large settlement.
