Doctor of Medicine Shangguan Qimeng's soul travels to high school student Tang Wan, and she is surprised to find that her crush on the male idol Liang Kaiwen has become her childhood sweetheart.
She happily accepted this belated romance, but bumped into Liang Kaiwen's previous wife Su Yao at a campus party - a name that made her feel inferior and escape.
There is an undercurrent behind the sweetness: in Logan's broken memory, her father is the leader of a drug smuggling and trafficking group, and she herself is a cold-blooded killer trained by the organization.
When Su Yao's father announced the marriage plan, Liang Kaiwen firmly refused: "I only want Tangtang."
Shangguan Qimeng had just breathed a sigh of relief when the pursuer's bullets had torn the night apart.
Her muscle memory was awakened during the bloody battle, and she killed several killers with her own hands. The cold killing instinct and the fierce love were fiercely torn apart.
She finally understood that this body had no right to be soft-hearted.
