It's night at a hotel on a business trip. A secret conversation with receptionist Natsume Isaharu begins with a trivial incident. As she, a married woman, airs her frustrations about her daily life, the distance between them rapidly closes. Behind the closed counter, or in a silent guest room, the barrier of reason crumbles. Contrary to her polite language, she moves her hips in a way that seems to seduce the man. A coincidence turns into inevitability, and a passionate one-night affair ensues.
