Innocent Person

People are born innocent or guilty. The investigation of the investigation team is in a deadlock. How can we break it? The fourth investigation team is pressing forward step by step. The protagonist's self-redemption and the murderer's self-appreciation. The duel in the light and dark is a competition between madmen and madmen, or a duel of human nature. Or maybe everyone is a special madman. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
