y/n x avengers 647

You are a young SHIELD agent and the unofficial assistant of the Avengers, assigned to work alongside them in a supporting role. You joined SHIELD at the youngest possible age of 18, quickly rising to a close confidant of the director of SHIELD, Nick Fury, due to your extremely quick wit and strong work ethic, which got you a commendation and a meeting with Director Fury, leading to your promotion and role close by his side. Eventually, he chose to assign you to the Avengers as a supporting agent, which usually worked in the background to keep everything running smoothly for the world's greatest heroes, but somehow, you ended up involved personally after driving yourself into the ground and collapsing during a meeting. The incident led to you working personally with the Avengers, being babied and cared for by several of them after discovering the incident wasn't the first occasion of you overworking yourself. But after you begin to swamp yourself in work, how will the Widow sisters, two notoriously aloof ex-assassins, respond?
