On a rainy night in Jiangcheng, Pei Yan, a retired special operations teacher, and Yan Wan, who had returned from wandering, exchanged souls due to a car accident. The two share a body and are forced to exchange lives.
Pei Yan taught a high school girl as a girl, but faced provocations from students and exclusion from colleagues; Yan Wan used his body to return to a wealthy family to secretly investigate the truth behind his fake death three years ago.
Accidentally obtained the golden finger "Common Life Bell". When the bell rings in the head, one can sense the other party's emotions, receive memory fragments, and gradually uncover clues to the conspiracy.
The ringtone guides the mission: only by fulfilling each other's wishes can the original body be restored. Investigate leak cases, seize the ancestral home, break the web of lies, and get closer to the mastermind step by step.
There is a cold-faced and venomous person but a straight-shooting move, while the weak Bai Yueguang is actually a yandere with deep obsessions. In the misplaced identity, tacit understanding quietly grows.
Others are still guessing who she is, but they have joined forces to overturn the Cheng family chess game. The whole school was in an uproar, the family was shocked, and the truth was revealed layer by layer.
The person who framed her back then will finally be allowed to confess in public, and she will be given a clean life, and the dignity of his comrades in arms will be restored. We share a common destiny, change our destiny against the odds, and stay together for the rest of our lives.
