You looked around and saw that you were in forest that was entirely covered in snow, you started to walk towards the bridge slowly.
When you were standing in front of it you heard footsteps behind you getting closer and closer.
"Human"-Voice said and you saw skeleton wearing a blue jacket as you turned around."Huh this scenerio seems a bit familiar"-He said but then just smiled- "Name's Sans. Sans the skeleton and I don't think it's really great time to fall into the underground since we have a problem with one dirty killer".
After he saw concern on your face he added-"Don't worry I'll keep my eye Sockets open so you're gonna be fine and uh may you try to take my brothers attention away from other kid? He would really love to have someone to solve his puzzle's and not just... Walk past them"
He then just walked away as you got past the bridge a few minutes later and took a look at a lamp that was. Actually human shaped.
You walked further and saw chest which had a glove inside.
Without hesitation you took it and putted it on and walked where road was leading.
You saw Sans standing next to someone who was probably his brother, Tall skeleton looked at you and whispered quite loudly to his brother -"OH MY GOD!? SANS IS THAT ANOTHER HUMAN!" -Sans replied-"It sure is bro.". Then taller one said again with excited tone -"HUMAN! I WILL CAPTURE YOU AND THEN I THE GREAT PAPYRUS WILL GET EVERYTHING I DESE- SANS WE NEED TO CAPTURE ONE OR TWO HUMANS?"- Sans then said -"One I think, so can't we just skip some puzzles for this one?"- Then Papyrus said -"OF COURSE NOT BROTHER! IM GONNA MAKE NEW PUZZLES FOR THAT ONE AND YOU GOTTA STOP THEM IN THAT AREA! PUZZLE TIME NYEH HEH HEH HEH!"- Papyrus left laughing and sans said -"Well kiddo want to have some ice dogs meanwhile we wait for my bro to get ready?"- You nodded confused.
You followed Sans to his sentry station and watched him as he started preparing hot dog. "would you like ketchup on it kid?"- he asked and when you shaken your head he replied -"Welp more for me". Sans gaved you hot dog and started drinking ketchup from the bottle, you didn't try to take a bite and just hidden it in your pocket.
"look I don't think other kid is really human"-Sans said looking at you-"So better try to stay away from them".
As you tried to look at him he was already gone, you just shrugged it off and decided to continue your way founding even more dust as you got past areas full of dust you saw footsteps leading to the other side of the bridge and you could see houses and other wooden buildings.
After getting past the bridge you entered shop which was empty looking at the note of the counter saying-"Please Don't hurt my family".
You decided to leave and head to inn which was empty too, after leaving it you headed to the library and started reading books about monsters.
After a few books you learnt something terrible, Monsters turn into dust after death. You realized that you were walking by remains of monsters killed by the other person who fell down here.
You left and just continued walking forward, walking through snowy fog you saw something on the ground. Papyrus's suit covered in dust. You looked at it Feeling mad and sorry.
Though anger changed to worry because you haven't seen Sans in a while.
You ran towards the next area feeling wet air on your face and hearing water flowing
