YES I KNOW I DIDN'T CHANGE MUCH! Frosttale is my AU, taking a joke of sans would be a sentient snow poff, to making an AU around it, asgore is sans, so while in story spin, he's happy, Frosttale asgore is depressed, cold, and the only other with fire magic. He's a happy boyfriend to toriel, which is to emphasize how upset he'd be if she dusted, going from "dirty brother killer" to "dirty girlfriend killer" in the "only kill papyrus" route.
