On the platform of the station, a middle-aged man was about to jump off the track to commit suicide. But at the critical moment, he was saved by a man named Kurosaki (Tomohisa Yamashita). While the man who attempted suicide was still in a trance, Kurosaki said coldly, "Uncle, you stepped on my money." The suicidal man was recognized by Yoshikawa Bingzhu (Maki Horikita) on the platform and asked why he committed suicide. The man said strange words, "I was cheated by a fraudster." Kurosaki offered to help the man get back the money he was cheated of, and introduced himself, "My name is Kurosaki, and my profession is a fraudster. I will eat those black herons who cheated you." Bingzhu did not trust the man in front of her, but she didn't know that she had been involved in a war of intrigue between fraudsters.
