Five years into marriage, a man still adores his wife Yuki. When a younger man hits on her during a shopping trip, he angrily drives him away—but imagining her following the stranger and having sex excites him instead of making him furious. Consumed by this new fantasy, he takes his unsuspecting wife to a street known for solicitation and leaves her standing there for an hour, eventually asking a stranger to join the couple for a free threesome.
