AI Sister Takes My Place

Lin Nian was once the most beloved daughter in the family, until an AI sister named Jiya came along. This docile and flawless substitute gradually took her place in the hearts of their parents and elder brother. She spent three years in a reform academy, where an invisible mold crushed her vibrant spirit, leaving nothing but an empty shell. By the time she finally became an obedient "perfect daughter" just like Jiya, her parents were only briefly surprised before growing used to the change. Her elder brother was the only one who still cared and tried to reach out — until one night. She sat alone and motionless in the darkness, while birthday songs echoed from the living room. No one remembered that it was Lin Nian’s birthday too.
