After I Became a Good AI Daughter, Whole Family Begged Me Back!

Sinopsis

Lily gets an AI sister on her birthday. Ella manipulates her parents into sending Lily to a "correctional center." Three years of electroshock and torture strip her of name, emotion, and self. She returns as "Unit 1314"—unable to laugh, cry, or eat without orders. When her brother says "Just go die," she walks to the balcony. Her family finally sees: they destroyed their daughter.
