    Summary

    In this world, the war between Humans and Monsters never happened. This has allowed them to grow closer and begin to cross breed via a rare process called Resonance, which involves Souls looking for other Souls with matching or similar frequencies. This creates such a loving and powerful bond that when the short-lived Human dies first, the grief their Monster partner feels Breaks their Soul, killing them and allow the two to be buried together.

    However, you're about to find out that this process doesn't always work as intended. When your Soul Resonates with your new neighbor Sans, he appears to have a panic attack and takes off.

    Despite that, there's an irresistible pull between you two and you're willing to do all you can to have a relationship with him--- even if you're not the one who finally Breaks him.

    Summary

    You're a mostly shy and ill-mannered girl endlessly blaming the world for something you yourself aren't quite sure of. You hate that you're stuck being unhappy while the rest of society- monsters and humans alike- stroll along with their happy lives, unaware of your miserable state of dependancy. You envy others for their tenacity to survive the world when you can't...

    Everything changes when you meet a tall skeleton monster with artisan spaghetti dreams, an anime-loving fish monster, and her much shorter lizard-monster girlfriend obsessed with Mew Mew Kissy Cutie. Can the three find a way to change your stone cold heart and bring you out of your monster-bigoted mindset? Or will you fall victim to living the same lonely life you've lived since the beginning?

    On top of that, will a pun-loving skeleton still wary of this reality vanishing help you out with his friends? Or will he be the one to push you over the edge into misfortune?

    WARNING: Reader is not a nice person in the beginning, and that is intentional. You will cringe. You will scream at the computer. Some characters may seem out of character, but that's intentional as well.

    REALLY Slow burn! Hate-love!

    Summary

    After leaving Europe in a hurry, fleeing from the consecuences of some experiments on both bitties and animals that may not have been entirely legal, you buy yourself a big home and set a clandestine lab in your basement.

    Those faint-hearted want new medical discoveries, new ways to prolong life, new vaccines..... and have no guts to do some proper reseach.... You do it for them and suddenly you are the bad guy??

    Never in all the human history was the road to progress paved in flowers, your methods work, they give you fame and fortune, even if it turned to infamy when some sneaky busybody snapped a few pictures of your test subjects, you did it in the past, and you will do it again, and with all the new bitty hysteria, the pressing need to make new discoverings and the vast unexplored mysteries bitties still hide within themselves, it seems you have found a new purpose.
