Returning home after a long time, the husband sees his stepfather for the first time since his stepmother's funeral. Though worried about his father-in-law living alone, he feels relieved to see him in good health. However, while taking a shower, he notices his underwear, which had clearly been placed aside, now lying on the floor—something feels off. Troubled and unable to sleep well at night, he dozes off in the living room the next day, only to be suddenly assaulted by his stepfather while unconscious. An unexpected reunion soon takes an unforeseen turn, leading to an illicit relationship under the guise of family bonds.
