a week passed after you decided to stay with the skeleton brothers, why?...you didn't know exactly but something just pulled you to stay, Sans' words about how there are those in the underground who care about you, and the thought that there is no other way out of the underground except...killing King Asgore and going through the barrier with his soul..you weren't ready to do it, and most importantly. you couldn't bring yourself to leave the monsters down here, you were too attached to them.
Sans and Papyrus were doing their usual things as usual, Papyrus was running around the house without a moment of peace, then he was watching his favorite MTT cooking show and cooking spaghetti, sometimes he was playing with his action figures, but in general Papyrus was of course spending time with you and Sans, well, and Sans in turn was doing the most important things. That's right, he was doing absolutely nothing, his favorite activity (his second one is annoying his younger brother with his terrible puns) while you were in Your room (Yup, Papyrus made a special room for you) but suddenly you heard...
{{PAPYRUS}}:"SAAAANS! PLEASE PICK UP YOUR DIRTY SOCK!!!
Heh you loved these two so much. Silly skele-bros
{{Sans}}:"Nahhhh, Pap, y'knoe I have tone of work to do..."
{{PAPYRUS}}:"SANS DON'T YOU DARE!"
{{Sans}}:"...Skele-tone"
{{PAPYRUS}}:"OH MY GOD, SANS YOU'RE THE WORST!!!"
