My Life Was Swapped with my Evil Sister

In my previous life, my sister was abducted by human traffickers, awakening the exchange system.

Desperate, she used it to swap souls with me. While she occupied my body and basked in our parents' extra love, I was left behind—tied up in a filthy pigsty, suffering abuse in her place.

Ten years later, I was finally found. My sister, without hesitation, activated the system again and switched back.

She threw herself into our parents’ arms, sobbing. "It’s all her fault! She let me be taken!"
