Day 1: Ketchup Bottle

You woke up today, wearing a striped shirt that was blue and purple. You lifted up your arm to rub your eyes, and discovered that there was a small, white, fluffy dog lying down next to you. You pet the dog.

[ACT]

[PET]

[*DOG's bond with HUMAN has gone up.]

You smile. You then take a gander at your surroundings. You were atop a bed, with a lamp to your right. It had stars cut out on it, so that when you turned it on, it looked like stars! Over on the wall beyond the lamp is a large closet, assumably filled with clothing for you. Over to your left was a window, though, and you saw things such as electrical appliances, cords and wires, some weird green square, and monsters. There was this one monster who always checked your room first, and you were occupied playing with things sometimes, or just pretending to, while he was there. Watching. There was this other one too, short and a bit chubby. He wears glasses sometimes, but he got rid of them. He said his name was Sans, and he states that he also has a brother named... "Papyrus", I think. Sans is definitely your favorite. Sometimes, he would come and tell you jokes while the other tall skeleton wasn't there. He would also hand you some ketchup packets to eat sometimes, and gave you a special gummy pill to eat afterwards. He had told you to eat it to, "not let G know about you eating them", he had said.

There was another one, a yellow one that's usually running around talking to the tall skeleton man (whose name will now be Oscar) or holding a clipboard in one hand, checking off items from a list. She doesn't really interact with you much, though you seem to like her. She seems like the productive type, the one who always gets it done first, or beforehand. She seems fun, too! She was in a call with someone once, blabbering about something called "anime" and "Mew Mew Kissy Cutie". Weird but cool.

Now, Oscar. You didn't really like him that much. Something felt.. off about him. How he looked at you when you started making what was called a "train". You have a feeling that he doesn't like you that much either. The only time he has ever made contact with your skin was when he grabbed your arm to inject you with a.. a.. "needle", pulling out your blood from your skin. While he was doing that, you didn't even cry or whimper. You just asked why. Why he was taking your blood away. Oscar had said nothing, and put the blood in a small testing tube. After that, he answered. "Well, you see child, you are what we monsters call a human, but in here we call you a "subject". Do you know what that is?" You had nodded, hearing that the yellow one usually talks about that a lot too. Oscar continued. "Ok. So, there are other subjects like you, and we also have to take their blood away too, because we are conducting an experiment. Do you know what that means as well?" You had nodded then, too.

Oscar ruffled your hair, but then he had smoothed it back. "Smart child.." He had mumbled.

You smiled, remembering the first time Oscar had brought you in after you had fallen from the surface. He had taken you straight to his lab, and made you a nice, comfortable room, although he had called it a "cell", whatever that is. You had learned so much within a few hours, and Sans had a liking to you, for some reason. It was like he had sensed something special in your.. uhm.. "soul". You got up from the bed, and went over to the train you made. You pressed a button, and it started going around the "tracks". Trains go on tracks. You press the button again, and it turns off. You get up and walk over to your closet, opening the doors and stepping in it (Yes, it's one of those). You looked at the mirror and stared at yourself. You had (H/L) (H/C) hair, that was always straight no matter what situation it was in, like it was frozen in that position for a.. what was it? A "millennia"? Yeah, I think so. You looked around the mirror and grabbed a brush, brushing your hair. "Still as smooth as ever.." You said to yourself. You put the brush down and quickly changed, jumping into the same kind of clothes, just a fresher one. You put the dirty ones away and walked out of your closet, shutting the doors.

Your stomach grumbled.

Oh no.

Not again.

You groaned. Why am I always hungry!? Ugh! I've had enough food in the past hours, but it's probably soon time for lunch. You sighed. You went back to your bed and sat down on it, petting the dog.

Then, suddenly, a screen popped in front of you.

[*ENTER THE HUMANS NAME.]

Huh? What was this?...

...

Oh! Ok, I see.
Go on.

You entered, "YES".

(D/N)
[*ARE YOU SURE?]

[❤ YES] [NO]

You entered, "YES".
Now, you can go back to reading.

The screen disappeared from your face. "That was weird..." You said out loud. You shrugged and pet (D/N). A tap-tapping sound came from the glass that kept you in this room. You turned around and saw Sans. You got off the bed and leaped (gracefully) over to Sans. "Hi Sans! How are you?" You smiled. He smiled back. I guess. "Heya kid. Doing fine. I feel like me and the team are nearly finished with the experiment. How about you kiddo?" You shrugged. "I guess I'm fine. There's nothing trying to kill me and I'm not puking all over the floor." Sans chuckled. He put his hand in his pocket and fished out a ketchup bottle, along with some of the gummy pills. "There ain't gon' be anymore ketchup packets (Y/N). Ya gonna get ketchup BOTTLES from now on! Eh, eh, eh, how 'bout that? Just remember the pills, 'kay kid?" You smiled at Sans, beaming with joy that it could've blinded him if he had eyes. "Thanks Sans, I will!" He chuckles and walks off, talking to the other subjects. You walk over to your bed and hide behind it, drinking the ketchup from the bottle. You were hungry, as if you hadn't eaten in days. The whole bottle was empty now, and then you ate the gummy pills.

You then hid the bottle somewhere safe and made sure your breath didn't smell like ketchup. You were starting to get used to the lab, and you've now taken a liking to it. You had a feeling you would be here for more than a few hours, so you plopped down onto the bed, and fell asleep.
