After the destruction and recreation of the universe, Mario's birthday is turned into a holiday known as Super Mario Day. One year, the evil Bowser attacks once again, and this time he has a horrifying new power: the ability to travel to other universes entirely separate from his and Mario’s own. Mario pursues Bowser into one of his portals and ends up in a mysterious new universe, where he meets a half-human, half-alien boy named Steven, who also happens to be a universe savior celebrating his birthday. Things unfortunately only get worse for both boys, as they soon find out that Bowser and an old friend of Steven’s have joined forces to fulfill an ancient grudge and conquer all the dimensions of the multiverse. Will Mario and Steven have what it takes to defeat this alliance, or will all existences be plunged into eternal darkness by two vengeful souls?

Summary
Haii hello, little intro before we get into the fic! My name is Juneau, and I will be your author. Please be kind this is my first fic since 2021… I saw there was a severe lack of Greg Universe x readers here (and everywhere) so this is for the Greg fans <3. (I will either be using no pronouns or they/them, so everything stays gender neutral also use of Y/n will be here)
In this fanfic you’re Y/N L/N and you’ve just come to beach city to open a hair salon! You’re 37 and a very big fan of the musician Mr. Universe ;).
I hope y’all enjoy!!

Or, alternatively:
Three times Steven was tickled silly during his childhood, and one time when he re-learns that sometimes, letting himself be vulnerable around family is okay.
