You've heard the stories, of the mysteries of a man who guides lost ladies home by night legend says his voice is like a demon of hell and anyone who's ever approached him has died. One night you get lost and you uncover his real story

It wasn't that (Y/N) hated monsters, oh definitely not, she just hated this one in particular. She absolutely loathed Mettaton.

Next person to comment on this monstrosity gets fucking vored!! × ❝You made your choice a long time ago.❞

You're in a world post-game of Undertale. Monsters were flooding up from the Underground, and no one was quite sure what to do with them. Most people knew of them, and expected it eventually. It was hard to get used to seeing these... People, you guess, but it became normal after the first month or so. They started getting jobs around, buying houses with their currency (which was Gold, and due to inflation of the new paper currency it was worth insanely more than normal money) and most of them were well off with their now nice lifestyles of upper middle class monsters. You're a simple girl, very short (barely under five feet), with a curvy figure and just over shoulder-length dark brown hair. You have a stupid job and a horrible college budget that made life kind of hard to do alone in your three-room apartment, which was the only thing close enough to the campus to get. It was meant for two people and a guest, but you had no one to move in with you. So, you put out a Cruggs' list ad asking for at least one roommate, maybe two. One person answered. Two monsters stepped into your life, and you have no clue how important these brothers were going to be to you- How important the always-smiling, pun-shooting monster was going to be to you. (Majority of the characters you're introduced to belong to Undertale. Writing by me, your character loosely based off myself, but only physically [height, gender, body type and size in general], the mental personification is just whatever happens.)

The barrier was lifted, the monsters were free but not accepted; hell broke loose, the wars were resumed. The monsters had no choice but to retaliate to the human's advances. Resources were scarce, the earth seemed unhabitable and the only way to survive was through violence. You lost all hope when you were forced to comply to such vile doings; being left alone by your family loosing them to a friendly fire during an escape. You were all alone; until he came along. ☆Violence, Cursing, Sexual Themes☆ ☆Gender-Neutral Reader☆ ☆Slowburn☆
