Dusttale: Murderer's Beginning

Familiarity

Sans woke up in his room, walking out of it.
He walked down the stairs as his brother, Papyrus was cooking, Sans entered the kitchen before-
[ * SANS! YOU'RE FINALLY AWAKE! ] - Papyrus said, turning his head at him.

[ * yup ]

[ * I AM ALMOST DONE COOKING LUNCH, SO PREPARE YOURSELF! NYEHEHEH! ] - Papyrus said, continuing to cook as Sans went over to the table, he sat on one chair as he put the pringles on their pet rock as Papyrus arrived with a plate of spaghetti and dinosaur egg oatmeal, he placed both plates on the table as he sat down on a non-existent chair, completely ignoring the laws of physics as they both started eating.

After eating, Sans got up from his chair as he started walking out of the house before Papyrus spoke:
[ * SANS, DON'T FORGET TO- ]
[ * recalibrate my puzzles, right? ] - Sans responded
[ * UH, YES. ]
[ * alright, i'll go recalibrate them ] - He said as he opened the door, closing it behind as he simply teleported to Grillby's
Meanwhile, a monster was peacefully walking through snowdin town as they just saw Sans disappear
[ * What the FU- ]

Back to Sans, he entered Grillby's, he sat on a table as he ordered some ketchup, thinking to himself

> [ * this day feels too familiar, it's as if i lived through it already. ]
> [ * maybe it's just me, or there's something different to it.

After Sans finished his ketchup, he told Grillby to put that in his tab as he teleported to snowdin's bridge, seeing the door open, he thought it was the old lady who finally decided to face off the colds of snowdin but no... it was a small figure, like a child.
The figure had a fully blacked out face, white hair, light gray clothes with dark gray stripes on their shirt and dark brown boots.
Sans thought this was a monster but... their aura made him sense that something was wrong, this wasn't a "human", nor a monster but it was... SOMETHING NEW
