Killswitch Protocol (A Doctor Strange x OC)

Kaleriya Romanoff was built to be a mechanical solution to human problems. To the Red Room, she was the ultimate closer: Killswitch. To herself, she was simply a girl trapped in a cycle of perfection where a single mistake meant ruin. She learned early that trust was a liability, and people only got close enough to hurt you. But when the Avengers lead her to the steps of Avengers tower, Kaley finds herself face-to-face with stuff she can't control. A strange man is sent to watch her for she is a new found threat to the earth. The man: Stephen Strange-a man who breaks every physical law she prepares for, and whose arrogant magic defies her cold, calculated lifestyle. He is everything she hates. And in a world where everything is falling apart, shutting him out might be one thing she can't perfect.

I do not own any of these characters except Kaley.
