After the Rift incident, an unspeakable rift appeared in the sky over the city, and whispers of the past seeped into reality. At zero o'clock every day, new rules of strange stories are synchronized around the world: you can't look back in the elevator, you can't pick up coins on the ground, you can't look directly at yourself in the mirror for more than three seconds... Violators will be physically deformed, mentally crazy, or swallowed by the rift. At the same time, the voice of a strange man sounded in everyone's mind - that was Shen Shiwei, a wanted gangster hiding in an abandoned shopping mall. He signs in every day to get filthy things, and has the forbidden ability "Forgiveness Mark": as long as he sincerely says "I forgive you" and accepts the other party's apology, he can erase the price the other party paid for breaking the rules. But the cost would be transferred to him, doubling each time. The first time, scales grew on his fingers, the second time, the whole arm was deformed, and the third time, the internal organs began to rot... A group of survivors cursed by the rules found him, and the hounds of the Taboo Administration also smelled his traces. He had to say "I forgive you" again and again with his heart exposed. When the price soared to the point of losing control, his body began to alienate into an indescribable existence - how many more times could he forgive?
