    Summary

    A little something based on the wonderful Brace For It by https://archiveofourown.org/users/Khurious/pseuds/Khurious

    I loved it so much I had to make my own take on it!

    This story is from Underfell Sans point of view.

    The world is done. Zombies roam the land and only the magically inclined are immune.

    Sans is on a mission.

    Going to try to be a slow burn, lots of drama and angst, topped with eventual smut and romance. Seriously intense attraction and denial.

    Summary

    (Y/N) is the second in command of the crew she was in. You were shown respect for it as being in second in command wasn't easy. You were on a ship going to enemy's land.

    You can't remember much other than a huge explosion happening on the ship.

    When you awoken you're stranded on a semi-huge island.

    Even if it means bumping into skeletons who have a thing for you on the journey to survival.

    Summary

    You are a day-care worker and you absolutely love your job. You get to teach and learn from the kids you work with, both monster and human children. If you could describe your current life in one word, it would be average. Not that you mind.

    That all changed, after you met a skeleton at the diner. And then another, and another....and another.....

    You never knew that life could be interesting.

     

    CrazyBunnylady and TheMsource inspired me to start writing. I promise I wouldn't write anything if I hadn't stumbled across their great stories.
