You're normal, unlike Frisk. You don't know what Mt. Ebott is, and you have no idea about the Monsters that live under you. In fact, the monsters haven't even escaped from the underground yet. But somehow, Sans' fate has still come to intertwine with you. How did this happen, and why? I'll try to add in some ReaderXSans, but I'm still not that great at Romantic scenes. xD
