Sans is getting abused by his younger brother, Papyrus. That's all I have to say.

Sans (Red) is a monster trapped in the nightmare that is Underfell. Brotherly abuse and the stresses of this world cause him to do the unthinkable, how will the Swap brothers react to the arrival of his broken mind? Possible trigger warnings? I don't know, read at your own risk. UnderFell and by extension Undertale doesn't belong to me. Go check Toby Fox's game on Steam for the original Undertale story! Criticism is encouraged!
