Su Tang, a popular female forensic doctor, took over the serial disappearance case, but all the clues pointed to her fiancé Gu Chenzhou. In the autopsy room late at night, the smell of Gu Chenzhou's usual cologne could be heard in the recording of the missing person's last phone call. And every time she searches for the truth, she always receives anonymous text messages on her phone: "Be careful of the person next to you." What's even weirder is that she found that in her memory of childhood drowning, the figure pushing her into the deep pool overlapped with Gu Chenzhou's figure. In the tug of reason and emotion, Su Tang gradually uncovered the conspiracy that had been hidden for ten years. Little did he know that this game of love and truth was a carefully designed game from the beginning.
