Sans has always been a lazy skeleton always being yelled at by his brother for being lazy, but one day and injured talking cat and her mate dead next to her begs to take her kitten and protect her. But before he can decline she was gone… He named her sunshine and brought her in much to his brother’s dismay for papyrus didn’t hate the kitten but in fact it was cuz he didn’t think Sans was responsible enough.(PS this takes place in a fused universe where Deltarune and Undertale are the same universe)
