My Redemption by LeahLovesPotterUndertale reviews

The Golden Quiche by Sophtopus reviews
For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.

Soulbound by kayixu
Sans has questions: Who are these people? Why did they kidnap him, and how do they know so much about him? In any case, they don't seem too dangerous. What's the harm in sticking around to find out? After all, his life has always been pretty weird. Why would that stop now? Sans' memory has never been the best. History's forgotten far more. Oh well, at least they have each other.
