My AI Sister Stole My Life

When Lily’s family adopted an AI sister Ava, she instantly became the outcast. Favoring the perfect AI daughter, her parents and brother sent Lily to a brutal reform academy to be "disciplined". After three years, Lily returns as a cold, obedient human robot who only follows orders. Her family soon regrets their choice, uncovers Ava’s malicious scheme and shuts down the cruel academy. Full of remorse, they try to heal Lily’s broken heart, while Lily eventually recovers and devotes herself to saving other traumatized kids like her.
