    Summary

    You're a terrible person.
    Which was pretty self-explanatory in it of itself, but nonetheless.
    Your descent into human tragedy had been anything but an overnight change, but, you know. Things happened, and the culmination of all your questionable life choices had led you to become the person you were now; a sarcastic, twenty-something-year-old nihilist with bleak prospects boarding on the line of alcoholism.

    So when you wake up after a night at a bar in a jacket that doesn't belong to you and a throbbing, all-consuming hangover, you're not exactly surprised. But when a certain red-eyed skeleton with a wolfish grin and anger management issues decides to insert himself into your trainwreck of a life, well. You aren't having it.

    Unfortunately, he's not taking no for an answer.

    Summary

    While doing some illegal drugs with a friend, you accidentally trap yourself in one of Papyrus's puzzles. He gets you down and brings you to his home, deeming it unsafe for you to go alone. You meet his brother and eat some welcoming spaghetti. It's one hell of a night and you're pretty sure something fishy is going on, so you keep visiting the set of brothers until you're able to find out. This ends up with you bonding with two socially awkward and touch-starved skeletons and beating up another skeleton.

    Summary

    You were accustomed to struggling through a world you knew you'd never quite find your place in. But when an encounter outside of your workplace lands you jobless, you soon find yourself swept up in a series of events that force you into accepting a ludicrous offer from strangers in order to keep a roof over your head.

    Never would you have thought your place would be right by their side, nor that they'd fight so hard to keep you there.

    Summary

    Moving from a backwater town to a city bustling with human and monsterfolk alike, some things begin to change both for the better and the worse. What was left behind comes back to bite at you in the most unexpected times, current progress being put in danger as a result. It's hard to move on, though it's equally difficult trying to stay loyal to what you believe is right.

    With an adoptive seven-year-old son and the remnants of a recent divorce in your hands, your goal is to move on and adjust to life with monsters, these becoming an important part of your life -- one of them in particular reigniting the spark you thought gone with your ex spouse.

    Summary

    Your father is a poor man, who has a plan that might make him rich. All he wants is money and to make his small family happy, so he hopes the Aster family is able to make that happen somehow.

    But you fucked all of that up for him because of what happened at that party. Or at least, that’s what you thought at first.

    Little did you know, one of the members took a liking to you… he isn’t exactly happy about that. He doesn’t like attachments. He struggles to give you everything. Struggles to feel things in general, and usually locks his heart away.

     

    You just had to open the cage.

    Summary

    "hey."

    You can't help but stare at the skeleton on your doorstep. He's quite literally soaked to the bone from the rain outside, droplets dripping off his hoodie in excess. He's trying to look like his usual laid-back self, but there's a tenseness to his grin and his eyelights look smaller than what you're used to seeing.

    "can i come in?"

    Summary

    In a world were monsters are forced into slavery and are controlled by collars around their neck, you never thought you'd be a part of the twisted reality. Your sick and owning a monster was the only way to keep you alive just that little bit longer. You hate the idea, Your Dad hates the idea, but it is the reality you know have to live with. It does help a bit to know that the monster your stuck with hates the human race and has no qualms about you dying. You do wish he'd stop spoiling your TV shows but it's not like your going to order him not to.
