    Summary

    This is a blend of a couple of ideas I've had floating around in my head for a while and finally decided to commit to one fic. The Royal delegation is heading north to sort out refugee status and establish an embassy in Canada's capital now that the barrier has been destroyed, but things take a turn when their carefully plotted trip is derailed by an almost fatal bus crash.

    Just as he's calculating how to get the monsters out safely as the vehicle is free-falling off of a cliff, he notices you doing something out of the corner of his eye as the bus slows it's descent. Did you just save them all?

    Summary

    ( Updates once a week whenever I can push one out )

    You ( the reader ) had shrunken to the size of 7 inches tall. This is the case for a handful of others. When the barrier shattered the pent up magic needed a few hosts and so the few which were the most mage out of everyone had been overloaded with magic. This was because it awakened the mage in you causing your magic to go wayward.

    Due to monsters being the cause of this and a few hand-picked monsters were picked to house the affected. It was thought that by putting them together the magic stuck in you would stabilize causing you to grow.

    You were housed with a skeleton. They chose to house you specifically with his brother both being boss monsters. Sans the skeleton was a scientist. You were constantly measured and smothered in affection... This is before well... It turned to love.

    Summary

    Based off my parent work, I was just experimenting with the idea of what happens if my crazy optimistic reader meets someone grumpy like underfell Sans instead of the vanilla. I initially had no intentions to continue this, but damnit, I suppose I will.

    Sans is a hardass, but our MC has him wrapped around her crazy little finger.

    By the way, she's a pretty hardcore mage.

    Summary

    The barrier is broken. Monsters are free. And a whole lot shit has gone down.

    Y/N and Red had dated for a year before he left her on the side of the road, literally. He saw his love as a weakness and so, he took care of it the only way he knew how. Abandonment.
    Meanwhile, Y/N was left to pick up the pieces of the mess that he had caused. She was trying to hate him but failed every time. She just had to accept the fact that it was over and move on. And so she did.

    Fast forward to 3 years later and Y/N is a senior in college, living with her best friend Jo, and giving life her full potential. Jo was telling her about a new boyfriend she took up over the summer break, whose name was Blue. She really wanted Y/N to come over for dinner to meet him to which Y/N happily agreed, excited for her friend.

    Until they pulled into a house Y/N knew all to well. And a skeleton she had been trying to forget.

    Summary

    You’ve dealt with a lot of rejection in your life. No matter how many times it happens, the sting still hurts. It’s the worst experience in the world.

    Or so you thought.

    But what if it turns out the opposite, having someone try to express his endearment toward you, ends up being the most unsafe, twisted, and damaging thing to your soul and your sanity?

One day when you were climbing the mountain out of curiosity you had discovered a hole where you guessed that the seven previous humans had used to commit suicide. You were about to leave when a voice called for your help. You had reluctantly answered it and wound up falling into the hole where a flower and a child were having a conversation.

    This is where your journey to save the poor souls of every monster and a human trapped between life and death begins.

    Summary

    Snowdin Forest is much bigger than most Monsters think. It stretches from one side of the caves to the other, blanketing the world with soft whites and deep greens. The only path may stretch from the door of the Ruins to Snowdin, but that doesn't stop the occasional Monster from living far, far from society.

    It sure didn't stop your family.
