Expiration date

Many years later

You where trying to catch your pet rabbit but tripped into a hole and fell into some flowers and some kid came to you to see if you where alright
"Hey are you alright "
"Yeah I'm fine where Are we and who are you" you asked 
" I'm frisk and who are you" frisk said
" I'm y/n"
" what a pretty name you have " she complemented you
" o-oh thanks I-I like your name too" you stuttered.
Frisk  helped you to your feet and took you to a house that somehow filled you with determination " w-where are we"
You asked
" this is goat moms house" frisk smiled
" goat mom?"
" ya" frisk took you into the house
" mom I'm home, and I have someone for you"
Skip time
"Come on I'll show you Snowdin" frisk said as she grabbed your hand and ran to the door to outside the ruins. As you and frisk walked out someone was walking behind you two.
"Sans?" Frisk asked
Then you as frisk where pushed into a bush by a girl with white hair.
" don't always trust sans frisk..." She looked at you
" who are you?" She asked
" I-I'm y/n" you said terrified
" oh net name I'm Miley I'll introduce you to my sister and bro later if you don't hang with sans!" Miley said
Then she disappeared.
Frisk had the most terrified look on her face.
" are you ok frisk" you asked frisk.
"I-I'm f-fine lets just go" Frisk responded to you
An hour later
You and frisk where at sans and papyrus's house talking then there was a knock on the door.
" who could that be." Papyrus got up to answer the door.
He opened the door and saw a girl around 13
" hey pap" the girl said
Sans eye turned blue
" oh hello Riley I haven't seen you in a while where have you..." Papyrus was cut off by sans pushing him away from the door.
"Papyrus go to your room NOW " sans yelled
Papyrus ran to his room and closed the door while you and frisk look around the corner to see sans at the door and not the girl that is out side the door.
" y-your dead how are you hear " sans freaked out
" I might have died but my corpse never rotted and it might have to deal with that soul in that doll you made of me, and yes I've seen the doll. It's kinda creepy of you to think about me that much. Yesh." Riley said
" Riley come on we have to get back..." The girl you and frisk met earlier came to get the girl at the door.
" Miley what the hell did you do to her. " sans asked a bet frightened.
" Riley what the hell are you doing here with this lazy piece of shit" Miley asked Riley
"I-I-I wanted to say I to papyrus." Riley said a bet disappointed
"Well miss genoside you don't have to call me a piece of shit ya know." Sans said to Miley.
Miley grabbed Riley's wrist and Riley started freaking out " no no no please stop Miley please don't" Riley begged which made sans freak out a bet.
" h-hey l-let h-her go m-Miley " sans commanded.
" sense when where you the one in control " Miley said as Riley and her disappeared.
" dammit " sans said.
