I was wondering if anyone could help. I'm looking for a fanfic but I can't remember the author, title, or if it's in FF.net or AO3. But (if I remember the story correctly), Steve got deaged by Loki due to a spell (which was aimed at Thor originally, I think) and Fury called in Bucky to take care of Steve. There was one part in that fic where Steve played with Clint (painting most of the tower area where they were) while Bucky was childproofing his apartment. Another (in the later part) where Bucky scolded after/during a grocery trip and Steve got sick after that trip.
I don't really remember if there were even pairings or such but I just remember that fic was cute but sadly, I accidentally did something which lost my bookmark of it before I could save or read it properly.
