On his way home from a drinking party, Ohta is invited to his boss's house, where he meets his boss's wife, Reiko, and becomes instantly attracted to her. One day, Ohta is asked to fix a computer at his boss's home and ends up alone with Reiko. After finishing the repair, he notices her napping. Overcome by her presence and unable to resist her allure, Ohta hesitantly reaches out and touches her. Startled awake, Reiko panics and tries to pull away, but then she whispers, "I'm just an older woman... are you sure you want me?" before passionately kissing him. In that moment, an irreversible relationship begins between them.
