The Day Everything Changed (GHB X READER X KARKAT)

Your name is (F/n) (L/n). You have been stuck on a planet called Alternia for 2 or 3 sweeps (4 or 6 years). You now live with no one other than Karkat Vantas and Krab dad. You were heading back to earth from a previous mission when you crashed onto Alternia -A planet just outside your universe. You lost your memory before the crash. All you remember is that you were on a mission to find extraterrestrial life in other universes. Everything else is a blur. The people on this planet aren't people at all actually, but trolls. Your ship is gone. Completely destroyed when you crashed. The trolls are....weird. They have horns and things called a Lusus? (At least that's what Karkat calls them) Granted, he is cute, but trolls and humans are strictly forbidden to be together without surviving a culling from the GHB. This is, of course is impossible, even for a troll. They just strictly forbid it so nobody has to get hurt, or at least more so than usual. Now, Your probably wondering when the story will start. Am i right?? Well....it starts.....NOW!! GO!
