Based on the Insta posts below

Bucky didn't like his metal arm but when he met a kid called Peter who told him that his arm was cool, he started to like it more and more.

**few days later**

"Hey Kid, what are you doing?"

"You'll see"
Was the response Bucky got from Peter.
Peter was sticking something to his arm and he didn't know what it was.

About 5 minutes later Peter said
"Finished!"

Bucky looked down at his arm and seen what Peter had done.
He put stickers onto his arm. Why he did it he doesn't know but it's nice.

"Thanks kid"

**later at night**

Bucky was getting changed in his bathroom when he noticed his arm in the mirror. He thought that the stickers were cool.

He needed to repay Peter for doing that.

A/N

So I know this isn't HYDRA but Bucky did get his metal arm from HYDRA (his first one (i have no idea what I'm doing)) so it kinda counts.
But I hope you enjoyed Bucky and Peter being happy. Also I'm nearly finished another one shot that I think you guys will enjoy and I'm thinking of starting another story where Peters class goes to Wakanda for a science/educational trip ( I don't know I just had he thought when I was brainstorming for ideas to do.)
