Hikari, a new announcer living with her boyfriend and producer Tetsuya, is a happy couple about to get married. One day, Hikari falls during a location shoot and injures her waist. For the injured Hikari, Tetsuya decides to call in a dispatched masseur. Contrary to Tetsuya's kindness, Hikari receives treatment on sensitive areas from the masseur, gradually feeling sexually aroused, and ultimately crosses the line.
