Five years into marriage, Aoi's once-gentle husband now takes his work frustration out on her. Her relatively flexible schedule and his endless overtime widen the distance between them until even seeing him becomes painful. Her only comfort is Yoshida, an older temporary employee roughly two decades her senior. As they spend more late nights alone at the office, she confides in him about her marriage. The night they finally cross the line, she begs not to go home, and he answers with a deep kiss before they lose themselves in intense, intimate sex at work.
