Hoping someone else has read this before and can help. I read a fic a couple years ago at this point. The last time I read it, it was still in progress, but it could have been abandoned or completed since then.
The main character is a teen who lives in the same apartment building as Bucky and maybe Steve, but lives with her aunt. One day, the OC is eating some sort of fruit, I'm 90% sure it was strawberries. Seeing the teen Bucky is reminded of pre-serum Steve and forms a bond with the kid. Bucky talks about adopting her, but there is some kerfuffle about it and the kid ends up running away with her cat. (please don't ask when the cat shows up, but Bucky refers to it as a demon cat which only likes the OC. Which really helps them keep bad guys away on the road. Before she runs away she meets Sam, Nat, and maybe Clint.
Either way in one of the more recent chapters it is revealed the cat is Loki and he is worried. I think she ends up going back to Bucky in the last chapter I read.
