Deadpool X reader

You signed up for a paid medical study because you needed the money.
You stayed because it worked.
Ten years after Project X was exposed and dismantled, its legacy resurfaces under a new name; Project Renewal. Quieter, cleaner, and just as cruel. When a serum designed to replicate regenerative abilities takes hold in you, the organization decides you're more than a success. You're proof. You're improvement.

They tell you there's someone else like you.
They tell you he's dangerous.
They tell you ending him would be a mercy.
Deadpool was never supposed to survive the experiment that made him.
You were never supposed to question the one that made you.

A slow burn story about manipulation disguised as kindness, healing that still hurts, and choosing someone not because you're the same, but because you want to stay.
