Fell!Sans x Fem!Short! Reader pt.3

*Your P.O.V
I woke up to this wooden thing...with an opening or something. Like a dog house,just bigger. Like a garden house of those things. Anyways,I ended up walking towards it,but something pulled me down,which made me collapse. I looked around and I saw these chains in my body and...A dog collar of some kind around my neck. I seemed to have been wearing new clothes,as my old clothes were black and purple,and now were black and red. I look for Flowey,who was sleeping on the other side. I yelled out, "Flowey!". Flowey woke up,and he quickly shushed me. I was about to shout back,but something caused me to hold it back. I saw a shadow..A tall man's shadow. He walked over to me and yanked on the collar,and he took off the chains. I put flowey in my shoulder,making sure to conceal him properly,as I dont wish for him to get hurt. This tall man pushed me in this house. It's warmer there,since the "hut" I'll call it,was cold,and outside was colder as it was snowing. I looked around and I saw this couch,and a TV. It seemed to be tidy,but messy as there was mustard bottles on the floor and a sock on the floor. It seemed to be a 2 story house. I panicked because the place was unknown. From upstairs,I heard this groan and this short-chubby skeleton with a black fluffy sweater,came walking down. The tall man was a skeleton as well. Just taller with red high heels,some black shorts,just like the other one, and some shirt of some kind. You could tell they were brothers,since they kind of seemed to live in the same house. "SANS,YOU LAZY-BONES,YOU SHOULD HAVE BEEN IN YOUR POST BY NOW. TAKE THIS HUMAN WITH YOU. I HAVE NO USE FOR THEM AS OF RIGHT NOW. I'LL JUST KILL THEM LATER AND HAND THEIR SOUL TO THE KING LATER AS WELL." Said the tall guy. "Aight,boss" said the shorter one,who I'm supposing is Sans and the other one is 'Boss' as he refers him to. I look at Flowey, and I see him close to crying and I comfort him quietly. The short skeleton glares at me and I freak out,holding onto the taller skeleton. The 'Boss' gives me this confused look and Sans gives me an even stronger glare. "B-Boss...He's giving me a look.." I said in a hushed and scared tone,pointing at Sans. Boss looked down at me with a surprised look that I had said Boss. He just scoffed with this proud look and pushed me towards Sans. "B-Boss..." I said as I pouted. This Sans grabbed the collar and teleported to his Post. He just slept,and occasionally drank mustard. I would talk with Flowey and hid,but Sans got tired of it eventually and told me to...Shut up,I guess. I was going to cry,but I decided to hold it in. Sans fell asleep,and I scuridly got up in my place and told Flowey i wanted to run and hopefully find a way out. So i ran. I ran as far as I could. I fell down every once in a while,but Toriel gave me healing items,so I was good.

-Time skip beauties.

It's been about two days since I ran. I stayed with Grillby's for a bit,and their hospitality I guess was kinder than Sans and Boss. I was actually...Grateful? I stayed in the kitchen most of the time,helping him out making food. And not even on the 3rd dat after,Sans went to the Kitchen and forced me out. Grillby's argued with Sans. But Sans won for some reason and took me to the house. He had slapped me a new mark on my face. I felt warm tears trickle down my cheeks as I yelled "I hate you!" as loud as my lungs would allow me. I ran upstairs but I didnt know where I was going anyways. So I ran to this room,and everything was messy. But I stayed there. Crying and crying until all I had were sobs. I saw a mattress full of mustard bottles and threw them off. I saw this jacket,and it was clean? So I slept with it. Flowey was sleeping there as well,but he slept apart,so I wouldn't crush him. I woke up with Sans on the side,rubbing his temples. I made a sound but quickly turned back and pretended to sleep. "Hey,what the hell kid. Why don't ya learn to mind your own business,like a good kid,why dontcha." I was SO NOT ready to be told my a skeleton what to do. "Why don't YOU shut up,asshole!?" I yelled back at him with red,puffy eyes,some tears still left from crying a few hours back. He looked with this surprised look,and he seemed to be ready to kick my ass,so I grabbed flowey and Jumped out of there. I panicked and cried and yelled to go back to Toriel. But I couldn't. I promised her I'd be fine.
-after a while of running-
I went to the waterfalls,which I had no idea of until I heard Grillbg talking about it with some monster when I was with him. I grabbed some water and drank. And I gave some to Flowey. "Thanks,(y/n)" he said gratefully. He jumped off to take a bath,but he got caught in the current and I ran after him. I jumped in the waterfall to catch him,but I couldn't swim. It wasn't deep, but it wasn't shallow either. I panicked and I grabbed Flowey before anything. I knew I probably wasn't going to live but giving Flowey a chance to live was much better than me. So I put him aside in land and tried to help my self up,but I couldn't. Flowey's vines were enough to keep me for a second,before it snapped. I went down and I yelled. I was knocked  Unconscious.
