Shen Zhiyi just signed a contract marriage, hoping to get out of trouble, but unexpectedly, from the moment she entered Gu Chengan's world, strange things happened one after another.
On their wedding night, when Gu Chengan saw the cinnabar mole behind her ear, he instantly lost control and went crazy. What kind of unknown secret does this cinnabar mole that has been with me for many years hide?
Later, when she mistakenly entered a forbidden area, a gardenia specimen quietly triggered fragments of broken memories in her mind. There are bizarre anomalies in the physical examination report, documents mysteriously disappear in the hand, everything seems to be controlled by a pair of invisible hands.
In the hot spring sanatorium, she actually read about Gu Chengan's unknown childhood. The experimental diary exposed in a secret compartment in the study made her break into a cold sweat. There is an ulterior truth hidden behind the "allergy" caused by the fragrance of gardenia.
As the investigation deepened, the Qingteng Middle School bombing case came to light. The DNA report showed a 95% overlap. The Y-shaped scar on Gu Chengan's lower back seemed to have a fatal connection. A mysterious conspiracy appears, and a battle for the password is imminent.
And Shen Zhiyi, amidst dangers and mysteries, gradually discovered that she was not as simple as she appeared. Who is she? Where will the substitute's awakening lead her and Gu Chengan's fate?
In this whirlpool full of lies and truth, can they redeem each other, or will they be cut all over by the sharp edge of truth?
