Do you remember the name of that fic because holy fuck? I want to read it

Y’know I don’t actually know the name of it! (I want to say it was “rocket man” or “moon man” or something?)

if anyone has a link to that very old johndave fic where Dave is an astronaut in deep space wherein time on earth goes faster that it does for him in space and he ends of dating (marrying?) rose and kanaya’s adoptive son John… hmu
