    You're 23 years old, you dream of being a famous Lyricist-singer-songwriter. You begrudgingly go to MEU a local college with your best friend Adelya where you almost immediately flirt with a certain skeleton and develop a magnetic attraction to the intimidating yet enchanting Dr. W.D.

    Summary

    Frequently updated and eventually long Reader x Underfell Story.
    For the first time, a grown up human has fallen into the Underground instead of the usual younger Souls, the last Soul needed for monster-kind to escape the Underground, but, it just so happened that the human would not give up so easily.
    Many monsters will hunt for the human's soul, they will succeed, they will fail and sooner or later, the human might be able to convince everyone of what they think is the best.

    The "You" is AFAB(assigned female at birth, so to say, female body in this story), their gender won't be mentioned nor will their real name(only nicknames), so you can think of them as yourself or whoever may come to your mind.
    -----------

    Content warnings:
    Smut and Romance (both fluff and rough), temporary Death, Violence.

    Multiple smut-scenes with the Reader and various characters from Underfell.
    Both slow and fast burns, very in-depth detail, especially during romantic/sexual scenes.
    Despite the high focus on smut and romance, the world of Underfell is not a happy place and violence, temporary death and angst will show up again and again.

    Summary

    They just called it the Facility. Humans went in and Monsters came out. It was always a freely given choice but there was no going back once you committed.

    Roman committed and now... he wasn't looking for a way back but a way foward. He wasn't a human any longer. Wasn't a girl. But that was all he had known for all his life - now he had to find a way to accept himself as both a monster and a man.

    Summary

    A dream SMP story. If any cc's are uncomfortable with this, I'll take it down immediately.

    “I made the first move, it’s your turn next.” I winked at him, and his smile turned up a notch.
    “How about one more kiss for good luck?” He cocked his head, his goofy grin making my heart do backflips.
    “You just got one. How about I kiss you again after you get back.” I tease, backing away.
    “I’ll be waiting.”
