    Summary

    Fresh passes you by on the street.

    Like a bug underneath his boot (heelys), he doesn't take notice of you.

    Not until he notices all of the Skelebros' and their interactions with you.

    'Feeling' a little left out, maybe he should do like everybody else and say hello?

    Summary

    You watched him unwrap his lunch, pouting.

    “C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know I only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

    Summary

    Hey there! I’m assuming the vast majority of you are looking at this crossover and thinking “what the actual fuck is this?” Well my friend...I have no idea. Basically what started off as a bunch of crack ships is now an RP with a friend of mine and we decided to post this mess online. So my dear internet weeb, do you wanna see Rika take on a cannibal? Or V stay with the soulless creator? Are you prepared to ship Saeran with the literal embodiment of death? Or Yoosung with a haphnephobic glitch? Well the me, your guide, as we happily march down the rabbit hole of hell that is...Mystic Skeletons!
