Shinobu (pseudonym) has been married for three years but has no children. Working as an office clerk, she shares her life with a husband who works at a construction site. On his days off, he sleeps until early afternoon, leaving little room for conversation between them. Lately, he spends entire days immersed in video games, and they haven't had sex in over a year. Amid this stagnant routine, Shinobu begins to question: "Is devoting myself entirely to my husband truly what makes a woman happy?" Seeking to break free, she decides to go on a two-day, one-night trip with a man she met through social media. A quiet, passive housewife who has always lacked initiative—especially in bed—undergoes a dramatic transformation during this journey. This intimate two-day record awakens something new within her. On their way home, overwhelmed by lingering emotions, they take an unexpected action.
