Shanggong Moran, the aloof top student in the Physics Department of University A, whose life creed is "There is a formula for everything, including the human heart." His life plan was as precise as clockwork, until a bizarre quantum laboratory accident caused him to exchange souls with Li Ze, the son of the school director and the famous "giant baby" in the school.
Overnight, the top student moved into a luxurious but depressing mansion, and faced a very controlling "helicopter mother" - Li Ze's mother, Wang Fengjiao. Wang Fengjiao planned Li Ze's life in an airtight manner. From dressing and eating to making friends and falling in love, every detail was under her control. And Li Ze, the spoiled "mama's boy", used his logic to turn the academic career of Mo Ran upside down in Mo Ran's dormitory.
In order to change his body, Mo Ran was forced to sneak into Li Ze's life. He had to use the logic of a top student to crack the "Mama's Boy" survival rules and fight against Wang Fengjiao's all-pervasive control. Not only did he have to deal with the blind date arranged for him by Wang Fengjiao and the forced "family business", but he also had to prevent Li Ze from using his identity to do stupid things on campus. In this frivolous identity exchange, Mo Ran unexpectedly discovered that behind Wang Fengjiao's desire for control, there was actually a shocking secret about Li Ze's life experience. And the seemingly useless Li Ze is not as simple as he seems. When the shell of a "mama's boy" is filled with the soul of a top academic, a counterattack using wisdom and passion to fight against abnormal maternal love and regain control of life begins.
