This Curse I Hold~

Curse wasn't always this way, locking himself away from the others, away from the very people he loves.... From the very people he caused to spiral to the point of no return. He used to be a regular old Sans, pretty sure he was actually an UnderTale copy... That was untill he got this curse that he holds... It wasn't noticeable a first. Sure his magic and appearance... 'changed', but it didn't seem to do any harm.... But then people he started making eye contact with either died, went mad or spiraled into Insanity..... His AU, his home, was no longer safe and it was all his fault.... It's much better for everyone this way, they would be better off without him... Now what's this kid doing here? Kid watch out-!
