    Summary

    When Frisk finished her story, barrier broken and monsters freed, she knew there was still a loose end, but she never expected everything to come unraveled before her eyes. Determined to save the only family she’s ever known, Frisk must stitch their lives back together after they are ripped apart at the seams and then attempt the impossible to stop it from ever happening again.

    [A story like this has been told before, in many different ways by many different people. Even so, I hope you enjoy it. Please know all major canon timelines and the music of Undertale before reading for the best experience.]

    Summary

    There are good days, and then there are days that.... aren't. Nozomi knows these a little too well. But maybe even these days have a purpose, if the arrival of some new friends has anything to say about it.

    Their outburst had no effect on the skeleton, who leaned against the wall, picture complete with half-lidded eyes and a lazy smile. "Don't I?"

    Summary

    What happens if you cross the Babybones and Judge Sans AUs And then stick in a little “Sans and Papyrus are not related”? This mess of a fanfic.

    Or, different characters wishing upon the echo flowers.

    Notes:
    This is my first published fanfic, so please feel free to leave constructive criticism!

    This will not update regularly, cos the author is a huge procrastinator, as much as they love writing fanfics >u<
