Three years pass, and three particularly strange things surface and change your life… for the better? Getting a chance to work in Toriel's future school… Being offered a place to stay upon being kicked out of your old apartment… And… Accidentally kissing a monster and having him become forward with his way of flirting with you? You're not too sure about that last one, but if one thing's clear, it's that you still remember how much he disliked you prior to the accidental kiss, so you're not about to give in so easily.

Living in a town close to the mountain range had its perks, and things certainly changed when the neighbourhood I stuck around in starts getting new residents. The only problem now is finding a better job. Luckily, a skeleton appears and tells me about a restaurant I can work at. I accept. And I soon run into a whole bunch of other skeletons that all seem to like me. Romantically. And I'm terrified of what's to come.

They hate whatever they can’t understand. A certain monk came along with similar feelings and dragged this random 11 year old with him. Killing all non-sorcerers never seemed like a bad thing, right? If only this sarcastic tween hadn’t been so careless during The Night of a Hundred Demons, they wouldnt be sitting tied to a chair. ─── ⋆⋅☆⋅⋆ ─── If you don’t really know who Chara is, in short they’re a chaotic neutral, spunky kid who has a certain liking for knives. I will be using “Chara” as the reader’s name, but of course you can replace it in your mind with any other name :) Gender neutral! I will not be using “she” or “him” to describe the reader.
