You two met because of Natasha. She had been wanting you to meet everyone since she joined the avengers. She made a promise that you would be able to meet them soon and she was right! The very next day they all met.
Steve~
Steve had saved you from your abusive boyfriend, instructing the man to never touch you again.Now you are like besties!
Thor~
You are a S.H.E.I.L.D agent, an assasin to be exact. One day after a mission in Chicago, coming back hurt your ears so much. You were greeted by a booming voice yelling at someone. Natasha laughed seeing you about to yell at who ever was yelling, until you saw a gorgeous guy with a giant hammer.
