Feeling uneasy, Kouji starts digging through Misaki’s room. What he finds are countless photos of her with another man, and videos of her having sex with someone he doesn’t know… Misaki had been cheating on him, right under his nose. Kouji is thrown into the depths of despair. Should he try to fix things with his wife? Pretend he never saw anything and keep living this life? Or should he destroy them both socially and take his revenge? …Tonight, you will make a decision.
