    A random Grillby x Reader story I wrote cause I was bored and actually really enjoyed making this. (Y/N) is a 22 year old woman that hates her job and wants something interesting to happen for once in her life. She never knew that going to her bar with her best friend Kattie would finally make (Y/N)'s wish come true. Also (Y/N) is a girl and uses she/her pronouns sorry. You can still read this regardless of whatever gender you are. Swear warning, I guess. Also there will be probably be grammer mistakes. Especially in the first few chapters and I'll probably never fix them cause I'm lazy. Sorry. Currently complete and I spent around 4 months on it cause I take forever to do anything. (39,408 words if your curious, I think, I might have done the math wrong.) (Cover art is not mine!) Edit in 2025: this fic sucks and is full of spelling errors and I hate it but I was also incredibly happy when I made it and I'm mad I'll never be that happy about something that I was making out of pure passion. Wouldn't recommend, but I'm still keeping it up because it makes me happy to think about how I was writing this. I should really make a male reader version now (I don't understand my gender identity anymore and don't know how to express it but I need to write gay fanfiction)

    The Human and Monster war is raging around you. Although you are a human, you refuse to pick sides. Your only goal is to save as many lives as you can. ~~~~~~~~~~~~ (I'm not good at descriptions, but basically Grillby is a general in the war and you find him half-dead in the rain. It's basically an apocalyptic scenario where everyone is fighting and the entire world has gone to shit.)

    NOTE: THIS STORY IS DISCONTINUED [Drawing on Cover by: SmokyJack on Deviant Art.] You clumsily bumped into someone on your way home from work, apologising as their papers from their arms and scatter along the ground. Feeling horrible, you kneeled down to pick their belongings up for them. As you handed the pages back to them, you realised that they were a monster, which spooked you a little since they haven't been on the surface for that long, and they were extremely rare to see on a daily basis...

    Y/N is a baker at Muffet's spider bakery. When Muffet hears that a nearby restaurant/bar sells better croissants than her, she sends Y/N in to get the secret recipe. Little does Y/N know what will happen next. This fanfiction is not written to be realistic nor is it to be taken seriously. It is a silly little romance story that was written for fun
