Top cardiac surgeon Zhao Xunguang and suspense writer Lin Muxue reunited in the hospital seven years later. Lin Duixue carefully planned a revenge with deep hatred for Zhao Xunguang's "betrayal" of his brother, which led to his death. She approached as a patient and disturbed Zhao Xunguang's mood with her distant attitude.
However, in the process of revenge, Lin Duixue discovered the encrypted USB flash drive left by her brother, and the clues pointed to the more dangerous business tycoon Gu Hongyuan. Zhao Xunguang ignored his own safety several times to protect Lin Muxue, and even blocked a knife for her at a critical moment, leaving his life hanging by a thread. On the verge of life and death, Zhao Xunguang finally revealed the truth: the "betrayal" that year was actually caused by Gu Hongyuan threatening Lin Muxue's safety. He was forced to leave and bear the stigma, and the money had already been donated anonymously to the victim.
When the truth came to light, the two men settled their differences and joined hands to fight against the real enemy. In the end, with the help of the force of justice, Gu Hongyuan was brought to justice, and many years of grievances were vindicated. The two people, who have gone through the test of life and death, spanned seven years of misunderstanding and pain, ushered in their own redemption and rebirth with love and perseverance. After going back to the dark side, they walked hand in hand towards a promising future.
