Misaki lives a life filled with love from her husband, Hiroshi. She believed that nothing could shake their love. One night, Hiroshi brings her colleague Kojima. After drinking, Hiroshi and Kojima start playing card games, and Kojima offers Hiroshi a bet. If Hiroshi wins, he wants 100,000, and if he wins, he wants to talk to Misaki alone. As a result, Kojima wins. Deceived victory. And Kojima, who got the reward of "time with Misaki", gambles to steal Misaki's mind and body.
