Hi! My name is Y/N! I recently fell down this mountain called MT. Ebott! I met a cute creature that turned out to be a monster. I stayed with this goat person I like to call goat-dad in this place called the "ruins" I just came out of the ruins to meet papyrus and sans. Papyrus is lazy and punny while his brother , sans , is cute and clingy. He acts really shy around me...I wonder why...
