Shen Yuan is a girl who lives a happy life. She speaks directly when she has something to say, without ambiguity or internal friction. She didn't expect that an interview column with senior executives she casually accepted would drag her into an elaborate death game. The interview subject is Xie Heng, the mysterious, taciturn and sharp-handed Xie eldest son in the Beijing circle. In her live broadcast room, a black fan with the ID "Deep Sea" can always accurately reveal her whereabouts, conversations and even unpublished interview outlines at the first time. What's even weirder is that the tone and words in "Deep Sea"'s messages are sometimes like men, sometimes like women, sometimes like crazy admirers, and sometimes like vicious enemies. Shen Yuan relied on her golden finger - the "ear of truth" to capture the true emotions and subtext hidden in the other party's words during the conversation. She discovered that Xie Heng himself seemed to be hiding something. As the investigation deepened, she was shocked to realize that "Deep Sea" was not a black fan, but the manipulator behind three personalities sharing one body. And this person was lurking next to her and Xie Heng. When Xie Heng strangled her neck on a rainy night, with unfamiliarity and pain flashing alternately in his eyes, Shen Yuan heard the truest voice in his heart: "Don't come near me... I will kill you."
