Cuckold game: "I'll definitely take your wife..."

Misaki lives a life loved and fulfilled by her husband, Hiroshi. There was nothing to shake up their love... I believed that. One night, Hiroshi brings in his colleague Kojima. After drinking, Hiroshi and Kojima begin playing a card game, and Kojima places a bet on Hiroshi. If Hiroshi wins, he wants to have him talk alone with 100,000 yen, and if he wins, he wants him to talk alone with Misaki... As a result, Kojima won. Deceived victory. Then, Kojima receives the reward of "time with Misaki," and goes on a gamble that takes Misaki's mind and body.
