Hidden in the night fog of the Huangpu River is a genetic mystery that spans twenty years.
Lin Xia never thought that Cheng Yan, his first love who broke up on a rainy night seven years ago, would make a strong comeback as the new CEO of Yuanhang Group. Unexpectedly, the hideous scars on his wrists and the cedar perfume he carried with him would actually involve the dusty secrets of human experiments of Cheng's Pharmaceuticals - the cries that echoed in the laboratory late at night, the twin embryos soaked in formalin, and the bloody truth behind the "accidental death" of her dearest sister.
When Cheng Yan's half-brother Cheng Yubai appeared with an illegitimate daughter who was 90% similar to her, when her lover Shen Ke who was supposed to be dead in the cryocontainer opened his eyes, and when the young perfumer Lu Zhiyao's genetic chain contained Cheng's code... Lin Xia was forced to get involved in a capital hunt in the name of love. The Morse code at the bottom of the gilt perfume bottle, the genetic key on the wings of the blue morpho butterfly, the eternal contract bound to the heartbeat frequency - all tenderness are lies, and all redemption is a trap.
