I walk into the large house. It felt friendly and happy. As if someone called this place "home." I wish I could say the same about my apartment in New York. I sigh at the thought that the surface might never be able to be "home."

The human, Frisk, seems very happy to see me. I guess they still remember me as the Sans I used to be. I force a smile. I was scared of coming here. I refused the first time Frisk offered, but they eventually got me to come over here.

"Hi, Sans!" they say very happily.

"Hey, kiddo," I respond as I pat their head.

Frisk was now seventeen, but that didn't mean they were still shorter than me. The fusion made me 5 feet and 6 inches. That was probably the only benefit from all this. I look around. I know Toriel should be here. If she isn't, then what's this kid planning?

"So, um, where's your mom?" I ask still looking around.

"Well, um, she went out. To, um, buy some groceries! She knows that your diet is much different than our's so she's getting more food," they say nervously.

They were lying. I could hear it in their voice. They apparently don't lie often. That's probably a good thing for Toriel. I continue to walk around the house. Frisk said I could stay the night. I smirk. This is an interesting experience. A teenager sneaking in their uncle into their mother's house.

"So, what ya planning?" I ask, hoping they would give me a truthful answer.

After a few seconds of nervous laughter, they say, "What are you talking about? I'm not planning anything!"

"Oh, sure. You let me in when your mother is away, and you're lying like there isn't a tomorrow," I say with a slightly more genuine smile.

"Fine, I want you to scare her!" they say a bit too excitedly.

I guess they don't do this very often. "Ya got anyone else on the prank?" I ask just so that we could plan it a bit better.

"Well, Papyrus, and a few friends of mine. They should be arriving soon," They respond, finally truthfully.

"So, where exactly is your mom?" I say looking straight at them.

They return the stare back with saying, "Um, the, uh, airport," nervously.

"What's she doin' there?" I ask, now only out of curiosity and concern.

I close my eye sockets and rub the start of the bridge of my nose. This is probably the worst thing this kid has ever done. They are wearing a striped T-shirt and some tight skinny jeans. I take my hand off my skull and lean on the counter.

I made a grunting sound, as the pain hit me. It wasn't that bad this time, but it sure did mess up what I was doing.

"Sans, are you okay?" Frisk asks after I started walking over to the couch.

"Yeah, I'll be fine," I respond in between my gasps for air.

As I walk slowly to the couch, I notice from the corner of my eye, the great concern of the teenager. Once I got near the couch, I let my body fall onto the soft cushions. Now laying down, I try my best to breathe deeply and smoothly. I failed, with my breathing fast and unsteady.

My jacket felt heavy. I decided to wear a turtleneck shirt that I bought a few months ago today, so Toriel or Frisk wouldn't have to feel awkward. I regret this fact. My shirt was overwhelming. It was crushing my rib cage. A low rumble of pain came out of my jaw.

"You don't sound ok, Sans. What's wrong?" Frisk asks as they carefully walk next to the couch.

"This happens a lot more often than what you'd think, Frisk. I'll be fine," I somehow get out of my jaw.

I had aches everywhere. Head to toe. It all hurt. Thank goodness for this soft couch. My feet were off the edge of the couch, so I didn't dirty the couch. I sigh.

"Do you need anything?" Frisk asks kindly as their concern runs throughout their veins.

"Maybe a blanket. This one might last a while," I say, making sure that I didn't have direct eye contact with them.

Frisk hurriedly left the room. I just laid there, comfortably. I turn over so that my body could be on my back. My feet were still off the couch. Finally, my breathing settled to a nice deep and filling pattern.

Frisk came back with 3 blankets, and says, "Will this be enough?"

I turn my head to look at them. "Yes, thank you, but I have a strange favor to ask you: could you please take off my shoes? I don't want your couch to get dirty," I say knowing that if I did move the pains would become worse.

Frisk only just walked over to me. They placed the 3 blankets on top of me that covered my whole body except for my shoes. Afterwards, they walk to the end of the couch that had my shoes and took them off.

They did not mess around. They knew that I had to rest. I guess I don't have a good excuse to move. I eventually fell asleep.

I was suddenly awakened by the sound of a shriek. It was Toriel. She drops the bag of souvenirs. I hear a crack from something in the bag, as my eye sockets slowly open up. Half of my face was covered by a blanket. "Hello, Toriel," I say nervously, sure that Frisk did not tell her that I was here yet.

"Oh my goodness, Sans. What are you doing here?" she almost immediately responds.

Most of the aching pains were gone, so I sat up. Most of the blankets that were on top of me fell off onto my legs. I smirk," Your kid invited me. They wanted to prank you. I'm so proud of them."

Toriel giggles," Well, I'm glad that you are here. Me, Undyne and Alphys are going out tomorrow. Would you like to come? I'd think they'd like to see an old friend again."

I rub the back of my neck, as I stand up. "Sure, why not? I might as well," I respond.

"Good! Anyways could you possibly know where my child has gone?" she asks, probably wondering if she should scold Frisk for trying to prank her.

"Nope. Been sleeping here for," I look at the clock, "three hours."

"Oh, Sans, you are exactly the same as before," she smiled and patted my head, before leaving the room to go search the rest of her house.

I sigh as if that were true.
