    “ya think i didn’t kick ya out for a reason?” His harsh voice was so loud it slightly shook the lamp.

    Wait. Rutting against a pillow, intense blush, anger attacks? Papyrus warned you about this.

    Summary

    Frisk makes it out of the Ruins with Flowey's help, but is quickly captured by a rather terrifying skeleton who likes to call them names and pick on them. They are injured and scared, but Sans isn't quite like Toriel and the other monsters in the Ruins. He might be rude, but he isn't cruel.

    Sans captures a human and knows his bro will be super impressed, but Frisk isn't like the monsters. They are scared but kind. Sans has always had dreams of things being different, where he wears his favorite blue jacket and his brother loves him, but could being happy really be possible?

    Summary

    Being mute, Frisk pays a lot of attention to hands, especially when they're signing something to Frisk. But, since Frisk is mute and not deaf, that sort of thing rarely happens and Frisk usually is just a part of one-sided Sign Language, one-sided Speech conversations.
    Which is why, when Sans, with hands with dips and chips like a heartbeat, starts signing out of nowhere, Frisk can't help but feel... normal. And being in Underfell, that's a near impossible feat.

    Summary

    Everyone keeps calling you Chara, yea you see the resemblance in the pictures but the name seems to be linked
    to some dark things you don't want to be tied to.

    Monsters now live on the surface and are now apart of normal society but they aren't welcoming you to the party anytime soon.
    You either have to welcome the history they attach to you or show them you aren't this Chara they claim you to be.
