When Ruan Ningli saw Yu Mengzhi last time, she was just an unlucky ghost whose mother died early and her brother disappeared. She drew Yu Mengzhi, who was like an immortal, and smiled and said to her that he would protect her from now on. Ruan Ningli didn't believe in fate or luck, but somehow she believed in this unreasonable man. He took her through other people's memories and solved a series of strange cases; he changed her destiny and made her a very dazzling person on Changle Street.

If he was a bad person, why did he care for her and love her so much? Everything starts from his past...
