In her previous life, her whole family was slaughtered and she struggled to survive. After being reborn, the legitimate daughter of a prominent family returned to life five years ago in an unknown body and became the legitimate daughter of the second wife of the Zhou family. With a drastic change in temperament, she started a new life. She outsmarted her aunt, regained her grandmother's favor, was filial to her parents, and raised her younger brother. She only had one "foolproof" cousin who always made things difficult for her, and even took the initiative. In this life, Zhou Youyi lived for herself and wanted to protect everyone she wanted to protect.
