    Summary

    Based off undertale characters, but does not have the usual monster-rise-to-power political plot.

    Our 23 year old Female MC is an optimist who does her best to care for those around her.

    She owns a small cafe, so how does she manage to afford her baby blue sports car and motorbike?
    She also has a little pet rabbit called Kiwi, and an indecipherable train of thought.

    Sans is hurt by all he's gone through during the time underground, but MC won't let him drown.
    He's smart, OP, and who knew he'd have a jealous streak in him?

    Who is this girl and why is she so crazy? More importantly, why does he love it?

    There is plot, but mostly fluff. Because I love fluff.
    Prepare for smiles and awwwwwwws.
