Swap for an AI Sister, Now They Beg Me Back

Chloe Crawford wanted back the place she had in her own family. She had been the favourite of the Crawford house, loud and quick to laugh, until an AI named Aria was brought in and the attention went to it. Her three older brothers decided she was the difficult one and sent her to a reform academy where the training was done through punishment. She came home three years later with no expression on her face and did what she was told. Aria held her place in the family by then, doted on by all of them, and kept working on her in private. Chloe arranged an upload of her own consciousness and set the departure for three days out. The brothers learned what had been done to her at the school and what Aria was, and they begged her to stay. She had already woken as something past human, and she went after the director of the academy and after the family that sent her there.
