The day before Tomoki's wedding day, he is falsely accused of sexual harassment. He loses his job and his fiancée leaves him. When Tomoki is standing on the ledge of a roof building, about to commit suicide, he sees a woman running towards him and screaming. She is attacked by a man with a knife. Tomoki tries to intervene, but is injured herself. At least he thinks so. This staged event, which takes place at the request of a customer, is called 'enjiya'. Tomoki similarly decides to take revenge on the people who accused him.
