Zhou Zeen is a Chinese working in a Moscow bar. He thought he was just unlucky, stabbed someone, fled abroad, and could go back after a few years. But Brother Scar doesn't see him that way. Brother Scar is the leader of the Moscow underworld. He has a long scar on his arm and flat corners of his mouth when he smiles. He felt that Zhou Zeen was "useful", so he gave him chocolates, taught him Russian, and called him "Zen". Zhou Zeen thought he was just trying to survive, but he didn't know that from the moment he took the first piece of chocolate, he was no longer himself. The police are looking for him, the gangsters are waiting for him, and he is in the middle, caught between a rock and a hard place. This is not a story about justice, this is a story about - you think you are an emotionless person just because you haven't met the person who makes you fall into it. When you meet it, you will know. You've fallen into it.
Concept: How a person is gradually changed in an extreme environment, and everyone pays the price for their choices.
