An unexpected intersection at a bar brings the keen designer Su Wan and the cold-blooded detective Gu Yanshen to get involved in a case. From jointly solving disappearance cases and secret room murder cases to uncovering the medical shady secrets of the "Shadow" organization, the two gradually fell in love during the dangerous investigation and agreed to go to the sunrise on the Erhai Lake together.
However, fate suddenly took a sudden turn - Gu Yanshen was terminally ill, and only a heart transplant could save his life. After successfully getting married, Su Wan chose to trade her life for the rest of her lover's life, but in order to save him from the guilt, she was willing to put on the mask of a "money lover" and used luxury goods and intimate photos to weave the illusion of betrayal to force him to give up. He relied on his cold mechanical heart to count down the days in pain.
Gu Yanshen mistakenly thought that he had been abandoned, and fell into decadence until he accidentally discovered the truth: the heart beating in his chest was the heart that his lover dedicated his life to; those dazzling "betrayals" were all fulfilled by her life. Filled with regret, he finally fulfilled their agreement and rushed to Erhai to reunite with her.
This is a love intertwined with detective suspense and deep affection of life and death. It uses the heart as a fetter, misunderstanding as a test, and sacrifice and love to prove the immortal love that transcends yin and yang.
