Summary
You’re just an average, happy human, going about life, trying to forge your way in the world. Fortunately, you’ve landed a nice job that pays well, you’re steadily and reliably working your way out of the debt you gained from moving to the city, and you found a great apartment (with a chill roommate, Sans, a polite skeleton monster with puns up his sleeve and an indecipherable gaze) for surprisingly little rent.
Everything’s fine.
And then, without warning, two more skeletons seem to show up out of nowhere at your and Sans’s shared apartment. The first to appear is Red, a hot-blooded, sharp-grinned alcoholic who isn’t shy to share his less than savoury intentions with you, with crude gestures and pick-up lines galore.
... And the second is a tall, broad, but quiet skeleton who immediately goes by the pseudonym Skull, sporting a huge crack in his head and a single, engorged red iris, that never seems to stop staring at you.
You’re not sure why both of them won’t leave you alone, or why Sans seems so desperate to stop them from interacting with you... But hey, what harm could come from it?

You were watching him again.
You couldn’t help it. There was something remarkably different about him when he thought no one was watching, like a mask slipping into and out of place. Here, in the dark, he didn’t have to perform for anyone.

Summary
Error’s hiding place in the anti-void has been discovered. While he, Killer and Dust look for somewhere new to turn into their base of operations, they need a way to ensure that none of those annoying ‘good’ Sanses teleport into their now-known base and attack, ruining everything they’ve worked so hard to achieve.
... And that’s where you come in. An unfortunate bycatch, a human Soul who happened to be in the wrong place at the wrong time... and now, a hostage, to ensure that nobody gets any ideas about bursting in. Until further notice, you’re trapped in the anti-void with three unstable, terrifying interdimensional murderers- and absolutely no way to defend yourself if they decide that they’re done with this particular hostage.
You need a plan. You need a survival strategy; you’re smaller, you’re weaker, you’re alone. You need a way to ensure that the monsters don’t turn on you and eat you alive.
And, well... luckily for you...
... they seem to be touch starved.
