The servant and the skeleton..(Horror! Sans x Slave! Feminine! Reader)

Y/N is the servant who works for the new queen of the underground after Asgor's death. Queen Undyne has treated her with cruelty. Y/N hasn't taken a single break, nor has she gotten much sleep. She wakes up at 4:00 am and starts on her work. But one day, a skeleton has come into the palace and begged the queen for more food. Y/N became more curious about the skeleton and felt sorry for him when Undyne refused to give more food for everyone.
