Thank you for reading. The story is about a girl from the underworld who broke into the human world to investigate crimes and encountered many challenges. She also encountered some small beauties in the human world. But the black hand behind the scenes reached out to her, and her life, love, friendship and even the whole world were about to be lost... But she was self-reliant and worked tenaciously to protect the people around her and the common people.
