In his heart, Lin Shen had a crush on a girl whom he had been secretly in love with for more than ten years and dared not reveal it to his mouth. For the sake of her, he went round and round and returned to Jian You. In a car accident caused by deliberate revenge, the two unexpectedly exchanged souls. The two became each other and were busy working in unrelated jobs. In order to maintain a normal working life, the identities of the forensic doctor and the criminal police were exchanged, so the two had to learn to accept and understand everything about each other.
The occurrence of a major case forced Jian You to take on Lin Shen's identity and face the murderer. As the case progressed and the two got to know each other better, they unexpectedly learned that they had secretly loved each other for more than ten years...
The complicated case far exceeded everyone's expectations. The bad news came that the criminal who had missed the case a few years ago kidnapped Jian You and brutally killed him in revenge for Lin Shen, who was an undercover agent at that time...
After sixty years of waiting for him, he was filled with regrets and died of mental disorder and depression. When he woke up again, nothing had happened, it just seemed like a nightmare. But why is there always some unspeakable reality in reality that happened a long time ago? Lin Shen, who was brave in his previous life, was afraid of hurting Jian You again and did not dare to express his sincerity to Jian You. Could it be that more than ten years later, the two of them would still miss each other in silence?
