  Summary

  You're a grad student at a house party. How many skeletons are you running into there? At least one you didn't expect.

  (This explains nothing. Please read if you like Sans/Reader romance slice of life with plot, character relationships, fluff and eventual smut. Underfell headcannon is being used.)

  (Time for a second note to reemphasize PLOT. Drowning in plot. Plot for days. Send help.)
