Lost (Gaster!Sans X Reader)
Okay so this is a SLOWBURN it has an actual storyline. I don't own any art in this (unless I say I do...) and most importantly I don't own you, nor Undertale
Any way storyline:
you are (y/n), a young girl (you are 18)who lives alone. Humans are waging war on monsters (you live out of what they call the 'safe zone') and you are in danger of dying. When you feel as if nothing good will ever come in your life, you got lost... Until he came.
Enjoy \(^ w ^ /)
