Back to the Future: 1999, Prisoner in the Mirror

This is a fanfiction based on Reverse: 1999. The platform's tags seem to be wrong for some reason, so I wanted to make that clear.

On the eve of the “Storm,” Sonetto narrowed her eyes and stared intently at the person before her. That face was achingly familiar, like a red-hot brand searing through the grief in her heart.

“Vertin…? N-no, impossible! She should still be at the Foundation receiving treatment. Who are you?!”

“What did I ever do to you? I shake off one group, and now there's another weird one… Forget it. If you want to know, come find out for yourself!”

The damp air, the biting cold… The feeling of remembering everything remains as vivid as ever. From the moment a raindrop fell toward the emptiness of the sky, the distance between them seemed farther than death itself.
