Lin Wei is a top expert in microexpression psychology, yet a deeply buried trauma has shut her off from her emotions. When she meets Xie Yan, a perfect, passionate heir to a wealthy family with an overpowering need for control, and he pursues her ardently, it all seems like fate.
But after a string of bizarre cases unfold around Lin Wei, involving people who lied to Xie Yan and ultimately disappeared or died by suicide, she begins to reconsider this perfect lover. The results of her tests send a chill down her spine: what he offers is no ordinary love, but a fanatical craving for "absolute honesty." No lie can escape him, and any deception brings unknown, terrible consequences.
As her investigation deepens, sealed memories gradually return. To her horror, Lin Wei discovers that her current trauma stems from witnessing Xie Yan "deal with" the first person who lied to him, many years ago. Behind his love lies absolute control and danger. As the line between love and fear blurs, Lin Wei must find the truth in the maze of her memories and decide: expose this dangerous lover, or become the last prized possession in his kingdom of "absolute honesty"?
