   Summary

   It’s been 10 years since the monsters were free, but the day of their freedom the one who set them free disappeared.... On the day of the tenth anniversary Sans finally is successful in finding their savior.... But things aren’t what he thought. Frisk doesn’t seem to want anything to do with any of them and Sans’ own words come back to haunt him as the human they had all thought was their best friend is terrified of them.... Can Sans and the others repair the damage they have unknowingly done to a soul who not only showed them compassion, but did so at the cost of herself along with having the inability to even properly see them... Will things ever be the same or will the rift between the monsters and their Angel be broken forever?
