I'm looking for a fic where Phil and Clint are best friends since childhood (Clint was adopted by Phil's neighbours) and Phil's moving away to college (I think)? There is some pining and jealousy on Clint's behalf (who is still a virgin? and Phil used to date Pepper?), but it all ends well (possibly thanks to Natasha's intervention?). The story was hosted on AO3.
I know it's terribly vague description, but maybe it still rings a bell? Help, anyone?
