Colors- Stucky x OC soulmate au

In the world where soulmates exist, you can't see any color. Once you meet eyes with the one you're destined to be with, all of the colors will come rushing in.

Mia Summers has been searching for her soulmate for years. She eventually stopped once she was taken hydra. She never believed she would find them, especially not while she was in hydra's clutches. Until one day she's sent out on an assassination mission, she must eliminate Steve Rogers and retrieve the winter soldier.

Steve and Bucky always knew they had another soulmate. They could only see each other in color and not the rest of the world. That was until Mia bombs their apartment and tries to capture Bucky.
