Ten Years Possessed, I Rejected His Proposal

My name is Lily Carter, a poor girl from the mountains. Ten years ago, I was used as a bet by rich boy Philip Brooks. A twisted game led to my soul being stolen by an evil spirit, and my body was controlled for ten whole years.
For ten years, I could only watch helplessly as "I" became Philip's perfect girlfriend—docile, obedient, never fighting back. The real me was trapped deep inside my own body, screaming silently.
The only person who remembered the real me was my childhood friend Marcus. He never gave up searching for a way to save me, no matter the cost...
Until that night at Carnegie Hall, I finally reclaimed control of my body. When Philip got down on one knee with a million-dollar diamond ring to propose, I did what I'd been wanting to do for ten years—
I smashed that ring in front of the entire world.
"Game over, you piece of trash!"
