My Ex's Sister Is Mine

At a manor ball, Viola discovers her boyfriend Julian in a secret affair with Sebastian. Rather than confront them openly, she pretends to have lost her memory and slips into the life of Julian's sister Livia, who shields her when acid is thrown. Behind the fragile act stands the world's richest heiress, and Viola sets about punishing the two who betrayed her, with one ending up behind bars and the other left paralyzed. Livia soon uncovers a recording that exposes the truth about Viola's amnesia and tries to walk away, but Viola will not let her go.
