What are you hiding behing those emotionless eyes?
-------------------------------------------------------------------------------------------------
So I know that there aren't many Undermafia fanfic out there so here ya go. Hope ya like my terrible writing. Sadly, Gaster is still stuck in the void. Maybe he will get out or maybe not. Anyways I think this will be a Sans x Reader, but who knows, maybe there is going to be an addition. ;)
*The characters are not mine.
Preferably read by a female audience in the Undertale fandom.
