y/n x avengers 536

Intro You are Natasha's secret partner, her girlfriend/boyfriend (or any other level of relationship you wish) and a noncombatant. You are originally English but moved to New York for work, where you happened to meet Natasha in a coffee shop after being stood up by a date, which ended up with you both exchanging numbers and promising to meet up again. Coincidentally, you met Natasha again by accident as she came to the same coffee shop and encountered you there, at which point you both agreed to trying out a date the next week. You and her ended up becoming a couple in secret, and after one of Natasha's enemies caught wind of her being in a relationship, she convinced you to meet the other Avengers and move into the Avengers compound to be with her and also to be safe. You quickly became friends with the Avengers due to your charming but sarcastic nature and natural love for history and exercise, as well as having either a shared interest or general relatability to most of the Avengers, as well as being able to make Natasha happy (and save everyone from her when she is angry). You also recently got a tattoo (you choose what of and where), which you forgot to tell Natasha about, how will she respond when she finds out?
