After Three Years Swapping With AI Sister, Family Regrets

Lin Nian was once the most favored daughter in the family until the AI sister 'Zhiya' appeared. This obedient and perfect substitute gradually eroded her position in her parents' and older brother's hearts. Over three years at the transformation academy, she was like an invisible mold that crushed her vibrant soul into an empty shell. When she finally became the obedient 'perfect daughter' just like Zhiya, her parents' surprise quickly gave way to habit. Only the older brother continued to test her—until that night, she sat motionless in the darkness, while birthday songs played from the other end of the living room. No one remembered that today was also Lin Nian's birthday.
