Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.

Summary
The dichotomy between black and white is your constant when it's time for you to meet the whole new civilization Frisk brought along with them to the Surface.
As a parent, it's not easy to trust others when they've hurt your child.
So when that new civilization decides they owe Frisk both for saving their kind and for still hurting them during that process, you've got plenty to say to them.
Forgive as easily as you once did with others during a stage of naivety? Oh, hell no.
They better have a good reason for hurting your child and an even better one for wanting to be a part of their family.

Summary
You don't even know how you ended up on your knees this fast. One moment Sans was making lazy conversation, half-lidded sockets fixed on you like you were the punchline to a joke he hadn't finished telling—and the next, he had you between his legs, cupping your cheek with one hand and tilting your face up with a touch far too gentle for how dark his grin had gotten.
"heh. guess you do like keeping your mouth busy, huh?"

Summary
The same day you fall down, the world changes.
Following a bright flash of light and the sound of something breaking, the Barrier is destroyed, the Underground is emptied, and you're left with no choice but to explore the Ruins all on your own, while everyone else celebrates (or protests against) the return of monsters to the Surface.
Upon reaching a snowy forest and venturing forward without a clear goal in mind, it feels like somebody's watching you, and you start to hear footsteps other than your own, too.
Just as it seems like you've reached the bad ending of a slasher movie, a friendly skeleton man approaches you and offers to pull you out of your predicament.
You're reluctant to let him help you at first, though his easygoing attitude and his tendency to joke around makes getting to know him a simple task.
Fast-forward to half a year later, and you're waiting for him at a diner to have your official first date.
Only to realize after an hour that you've been stood up.

Summary
Cherry Sweet is a rather unconventional performer at a club like 'The Velvet Crop' with her thick thighs and plush stomach, but she does well enough for herself. The patrons enjoy a bit of variety, but what will she do when she attracts the attention of a monster--and a mob boss monster at that?
Featuring a 1920's vibe with music from the 20's-60's, a meet-not-so-cute developing into a partnership, and a spitfire, plus-sized FMC. I hope you all enjoy!
