    Summary

    Tiffany Loves was nice and pretty, looking for a place to rent a room while attending college to be an artist. She finds herself staying at a mansion with eight skeletons and becoming friends with all them. In fact thanks to soul bonds she has become a lot closer then friends to them…

    This story though is a lot less about her and more about a certain assistant, the student majoring in engineer at the same college and assisting Sans in fixing his machine. His also nice as far as he knows, not bad looking, but never the focus of much attention. The stand-by friend for skeletons when Tiffany was too busy. He was ok with it because one specific skeleton appeared to like him a lot and he liked them very much as well.

    But then he finds out he was second fiddle even with that one skeleton compared to Tiffany. He leaves the assistant job swearing to have nothing to do with skeletons. Something goes horribly wrong with the machine though and nothing is going to be the same again. A little twist on the typical reverse-harem story.

    Summary

    It's been years after the emergence of the monsters from the Underground and everyone just wants to continue on with their lives on, both monsters and humans. But it's always been the violence, blood, dust, and guns that make sure everyone knows that it's the gangs that rule these streets. Enter Adonis, a mysterious young man from nowhere who just wants to live as quietly and peacefully as the city allows him to. Working as a teacher by day and bartending at night at the swankiest club allows for a roof over his head and food on the table, but one fateful night changes everything. As it always does.

    "Red lights. Inside empty sockets. My body lurched backward as I saw his eyes, or what should’ve been his eyes. His face wasn’t human, not even close."

    Sans always has a way of greeting a new pal. But there's something drawing him to this one guy, more than he'll ever know.

    Summary

    A blind human spends most of her life attempting to be a successful musician despite her parent's wishes. When she finally does make it big, they try to make room in her life for themselves just to make some money. She goes to a local bar by the name of Grillby's in an attempt to relax from all the chaos that her parents brought with them. What she doesn't realize is that the bar is primarily a monster bar, and that's when she meets Sans. After that, her life is thrown for a loop as she befriends a large cast of different skeletons, and inevitably ends up moving in with them. (Slow update speeds as I can generally only update on school breaks.)

    Summary

    Asra was raised by monster hunters. They had their origins in the war that time forgot, when the human-aligned mages locked away the monsters underground...or at least the ones they were able to catch in time. Those who remained went on to earn a place in various local legends, scattering all over the world for their own safety, and largely fading to the realm of myth. This earned her family none too good a reputation in historical circles, as they continued to insist on their version of events.

    When her mother sent her to investigate the Mt. Ebott disappearances, she wasn't expecting to learn that the old stories that ruined her life growing up were true. Now she had a choice to make....

    Summary

    The monsters broke free. Only, they weren't what we had exactly expected.

    Now the monster mafia runs things by their books. I work at a bar in the city where they're most active, and one skeleton in particular has his eye lights set on me. But I'm not going to make it easy for him. He's the biggest name in the mafia, and I'm not gonna just bend to his will just because of that.

    Oh, no. I'm gonna make this drag out until he leaves me the hell alone.

    Or will he?

    Summary

    Complicated. You hated that word, really - when someone told you things were ‘complicated’ you knew that they had no idea what the word really meant. And yet, it was really the only word you could use to describe your life. “Complicated.”

    Your secrets had secrets and you were towing around a mountain of personal baggage. There were very few people in your life that really understood you and you were perfectly content to never interact with anyone else unless it was absolutely necessary - because of all the things you disliked, people were at the top of that list.

    Enter one Sans the Skeleton, who is very much aware of what the word ‘complicated’ means. Looking back on it, it doesn’t surprise you at all how hard you fell for him. You didn’t believe in happy endings, but you’d be damned if you didn’t give him one - no matter how many tries it takes.

    ~Updates (hopefully) every other Saturday~

    Summary

    His skull shines from the sun as he looks through the glass at you, his face wearing a bright but also lazy smile. He gives a small wave, which you returned politely before settling back into the pile of pillows.

    He seems to take the hint and turns around, engaging in conversation with the rabbit monster. While his back is turned you take a closer look at him.

    He wears a blue jacket with a grey hoodie, black shorts that have a white stripe down the sides and pink bunny slippers. His stance screams lazy and uncaring of the world around him. Cool.

    You haven't even said a word to him, but you already hope he sticks around.
