Reunited With a Twist

My parents have found their birth daughter. They're reunited thanks to her face, which is almost identical to my mother's.

After weeping in my mother's arms, she slowly raises her head and looks at me. Her gaze is filled with hostility.

"You've enjoyed what's supposed to be mine for so many years. Don't you think it's time to give it back?" She doesn't bother concealing her hatred for me.

My parents are still bawling their eyes out over being reunited with her. In the next second, their sobbing abruptly stops. She doesn't notice it, though.
