Chapter One

D-84, a H.Y.D.R.A. assassin, works alone. Loneliness is normal for her. At least, until she meets the person who will change her life for good. Loki.
Set after the battle of New York in Avengers 1. Everything after that point is based on my imagination and does not necessarily comply with every detail of the MCU.
