Obstetrics nurse Lin Xiao has already noticed abnormalities in the fetus in her sister's belly from a strange B-ultrasound. The elder sister who lost love at an advanced age insisted on giving birth to her child An Qi, but little did she know that this girl who could tell lies right from the moment she was born was born with the ability to understand everyone's secrets and predict life and death. The whole family was enveloped in endless truths, and her sister eventually passed away due to an accident. Lin Xiao shouldered the burden of raising her, and accompanied An Qi, who was aware of the darkness of the world, to find redemption and an ordinary way back in the pull of secrets and love.
