In her previous life, Rong Zhuo was the strongest esper, shouldering the hopes of all humanity and working herself to the bone every day to kill the otherworldly creatures. Just as world peace finally arrived and she was ready to retire, she suddenly transmigrated into a book.
In the book, Rong Zhuo went missing as a child and was not found by the Rong family until she was eighteen. The whole family thought she had turned out badly and despised her, while doting on their adopted son.
Hoping to earn her family's acceptance, the Rong Zhuo in the book was willing to obey any demand they made.
To avoid marrying their precious adopted son off to Nian Chen, the Nian family's twisted, brooding illegitimate son, the Rong family ordered Rong Zhuo to take her younger brother's place as the bride.
Yet not long after the wedding, the Rong Zhuo in the book died for reasons unknown.
Faced with a plot that had her getting married as soon as she arrived, Rong Zhuo didn't care. A bed is a bed wherever you lie down. As long as they paid her in full, she could take the money and go on vacation after the wedding.
Just as the Rong family was celebrating getting rid of a burden, otherworldly creatures suddenly began appearing on Earth. Humans gradually awakened special abilities, and Rong Zhuo, the person they had looked down on, had already become the chief of an esper organization.
Rong Zhuo: "Why won't these creatures leave me alone? I transmigrated into a book, couldn't they give me a break?"
Nian Chen: "Huh? Where did my wife go this time?"
