I enjoy reading this oneshot and I'm glad to see you writing again! The superhero prompt fits pretty well with Encourageshipping. I love the twist at the end where it's ambiguous and the readers can interpret whether Yugi is a superhero.

This was an awesome one-shot that has me wanting it to be a longer story. There is so much that needs details explained :-)
I hope you take it as a suggestion, this is your story and I will not be disappointed if you leave it as a one-shot :-)

Welcome back. I was wondering where you were!
That was very sweet. It felt like the early manga, when Yugi's alter ego was more like a superhero than a Pharaoh.
The comparison between the two kisses was good. I also imagine they would kiss slightly differently, even though they share the same body.

This was really cute. Loved it.

I think they'd make awesome superheroes!

Spiderman. That's what came to mind. The part where MJ was kissing him in alley. Your descriptions have gotten much stronger and more vivid (if possible.)
