Y/n has been through the world resetting itself again and again unaware that the child ambassador,Frisk, has been doing it. They remember bits and pieces of each reset and they've been though enough to the point where they're emotionally numb. Ummm Idk what else to put other than this is an Undertale sans x reader!! Also lots of bad grammar!! I IN NO WAY, SHAPE, OR FORM OWN ANYTHING UNDERTALE!
