Chapter 1: Who is that?

Y/N is familiar with the Avengers because of their great uncle Steve and a short-term stay two years ago, but a new face on the team and an old flame on the compound is bound to throw a curveball their way.

Y/N = Your name
Y/L/N = Your last name
Nibling = A gender-neutral term for niece or nephew
✩ in the chapter title = Mature content

I do not own any of these characters outside of Y/N.
