Natasha Romanoff was never particularly fond of Y/N. Ever since you joined the team, there was a tangible rivalry between you both. Apart from this, you were ignorant toward one another. One night, after a dangerous trip to Budapest with Clint, you return to the compound injured and weak. Natasha, who appears to have been waiting expectantly, gently cleans you up and scolds Clint for his irresponsibility. Since then, your feelings for the Avenger becomes skewed, and when Tony assigns you both to a mission in Edinburgh the dynamic in your relationship changes. - Set during Infinity War / Endgame (not plot accurate) - Smut warning (!) - F x F
