In my last life, my real daughter caused me to be misunderstood by my brother. After my rebirth, I abused my real daughter

On her eighteenth birthday, Blair Sterling's world shatters when a girl named Chloe arrives at Sterling Manor claiming to be the family's true heiress, swapped at birth by an adoptive mother. Blair's four obsessive brothers, led by eldest Julian, refuse to let her leave. In her previous life, Blair's willingness to step aside enraged them; they locked her in a lightless room, and she burned to death in a fire. Now she has awakened one week before Chloe's arrival, determined to rewrite her fate.

This time, Blair plays the devoted, dependent sister, reminding her brothers of a prophetic nightmare and securing their promise never to send her away. When Chloe moves in after a DNA test confirms her identity, she drops her tearful facade and threatens Blair, demanding her room and her place. But Blair knows Chloe's bruises are not from a drunken adoptive father, and she quietly holds the truth over her rival while navigating her brothers' suffocating control.

Trapped among possessive siblings and a scheming newcomer, Blair must execute the plan she never had the chance to begin.
