   Summary

   College is never easy, especially when you're majoring in Astronomy.

   And it's ten times as hard when you're shoved into another universe full of monsters, humans, and skeletons who are dying for your attention.

   You haven't been into Undertale AU's and the hot skeletons in them since you were an awkward teen...
   And now that you're an even more awkward adult, all it took was you being bored one night, and finally opening AO3 for the first time in years to get isekai'd into a world your younger self would've died to go to.

   What are you gonna do?
   And why are they all still so hot?!
