  Summary

  Reader finds a blue necklace with a blue echo flower laced onto it, that glows. Turns out it was NOT a normal necklace. Don't pick up stuff you don't know where came from then??.. You might regret it.. Or maybe something will change for you.

  You also have a huge addiction to Marble Sodas..?

  Yes! You heard that right folks!
  The name originates from the Codd-neck bottle used for the drink, which features a marble inside that seals the bottle and keeps it fizzy.

  Maybe you just need to stick to you and your sodas..

  Instead you end up dying—But you aren’t done here yet.

  Sans aus x Reader.
  1 - 20 : Human!
  20 - 35 : Ghost….?

  OLD STORY NAME: FM (Fuzzy memories.)

  This fic is heavily inspired by my childhood and the amount of ghost stories I’ve been reasing… OH I MEANT READING* WAAAH•̩̩̩̩ᯅ•̩̩̩
