YAYYYYY NEXT CHAPTEEEERRRRRR

GUEST: haha well, honestly I don't either! Maybe this will help...? I'm leaning towards it making it worse, though, muahaha! I'm really glad you like G! And Sans... well, I'm really glad I haven't made him OOC! I know I hate it when they do that. Haha, when I'm writing them I have the same problem! No puns in this chapter, I think... but next chapter maybe? I dunno. I do love puns tho. OH! There is ONE PUN!

The next morning, you got up like usual (at around ten, because Sans isn't the only lazybones) and grabbed some Froot Loops. Then, you crashed in from of the TV and watched anime until was time to go to Sans' house. Around five minutes after started,
though, you got a call. "Hello?"

"*Why hello, my child!" You smiled, sittingup a little straighter at Toriel's voice. "Hi, Goatmom!" You heard giggling over the phone nod smiled even wider, knowing you were on speaker. "Hey Frisk! What's up?"

"Come over! Come over!" She cheered, and you could hear her jumping up and down. Toriel laughed. "*Now, Frisk! I have told you not to jump on the couch! But yes, (Y/N), Frisk and I would enjoy entertainingyou today, if you are not too busy." Hm.
Well, you did have two hours. And you could get some PIE! "I can't stay for more than a few hours, but I'll be right over!" After a few goodbyes and such, you got dressed, grabbed your bike, and started riding the few blocks down to the
Dreemurr house.

"Hi!" Frisk chirped, flinging the door open and hugging you tightly. You laughed and hugged the 11-year-old back. "Hey, kiddo! Hello, Goatmom. Where's Kinggoat?" You hugged Toriel as well, enjoying the fluffy. She had pieces of pie set out and everything!
You love your Goatmom.

"*Gorey is watering his flowers outside. He will be in shortly, I believe." You three dug in to the pie, smiling and laughing. It reminded you of when you'd met them first.

It was a few weeks after you'd began as Papyrus' tutor, as well as taking tutoring of your own from Sans. Papyrus had quickly become one of your best friends (actually, only friend, to be honest. Crayon and Arix weren't in your class then.) and Sans was
still... being Sans. "*WOWIE! I JUST REALIZED YOU HAVEN'T MET THE REST OF OUR FAMILY, GOOD HUMAN FRIEND!" You had laughed at Paps' excitement, (though why, after being subjected to it for several months, it hadn't yet lost its cuteness, you didn't
know) and smiled. "Well, okay them. Who's your family?" Papyrus practically dragged you to the Dreemurr's house in his sports car. Back then, you didn't know Sans could teleport, so it was surprising to find him already there.

"*Well, hello, Papyrus, Sans! And- oh, who is this? Hello, dear. I am Toriel. It is nice to meet you, what is your name?" You had been startled to see Toriel. Not because you'd never seen a monster like her, but because you HAD. Toriel, Asgore,
and Frisk- all of whom were standing right in front of you- are constantly on the news and quite famous as memes on the internet, in the papaers, and anywhere else you could possibly be famous. And you were meeting them!

"Wow... Hi! I'm (y/n), It's really nice to meet you!" You stuck out your hand to shake, but the Queen took you up into a big hug. "*That is a lovely name!" Really?, you thought to yourself with an inner smile, That's awesome! "*Thank
you, Mrs. Dreemurr."

"*Please, call me Toriel, or whatever you like! There is no need to be so formal, my child."

And from that point on, you were practically adopted by the King, Queen, and (also adopted) Princess of the Monster Kingdom. It was EPIC. Later you realized Sans had been carefully watching your reaction, and you're pretty sure that's part
of the reason he warmed up to you afterwards.

"*Dear, Gorey and I haven't hade a date night in a very long time. I was wondering if you could watch Frisk for me tomorrow?" Toriel asked tentatively, as if she actually thought you would ever say no! "Of course, we'll have tons of fun! We can invite
Alphys and Undyne over, and Papyrus and Sans. It'll be awesome!" You grinned, but when Toriel thanked you you could tell she noticed the name you'd left out. She sent Frisk off to play with Asgore as her face grew more serious.

"*(Y/n), I'm afraid I have another request to ask of you."

"Go ahead, Goatmom! Anything." She hesitated. You were getting really curious now.

"*You know Sans' brother, do you not?" You were a little confused. "You mean... Papyrus?" Toriel sighed. "*No, Gaster."

"Oh." You felt yourself closing up, and had to force yourself to be willing to listen again. "What about him?"

"*My child, you have helped Frisk to have another human who truly loves her. You have taken care of Papyrus, in his schooling and in his life, being a friend like he has always dreamed of having. You have managed to break through the walls Sans has put
up, and because of this he is happier, and his smile is more true than I have seen in a very long time. So now... I ask you... to do the same for Gaster." What.

No.

Why would she ask this?! You can't STAND him! He is a jerk, and rude, and the meanest, most condescending- "*My child, I see the look on your face. I know it will be hard. But before you tell me your answer, please
think. That boy is going to get into trouble, serious trouble, I fear. He will not listen to me, or Asgore, or Sans. He will not listen to anyone. Please, you need to make sure he stays safe. If not for his sake, then for me. And, if not for me, then
for the rest of monsterkind." She paused, looking at you seriously. You both knew about the fights Gaster got into. Everyone knew he was involved with the more dangerous of monsters; the ones who wanted to take back the surface from the humans and
give you a taste of your own medicine. They were the reverse Anti-Monster Gang."*And if not for me... do it for Sans. What do you think will happen to the two brothers if the third is accused?" Toriel'svoice was filled with worry, not
just for Papyrus or Sans, but for Gaster too, for every monster and human.

You knew that whatever Gaster did, there was no way he could start a war... by himself at least. But he could certainly make life miserable for plenty of local monsters and humans. God knows he did to you.

You agreed to watch over him as much as you could stand. Goatmom was put at ease, and smiled again. "*Thank you, my child."

"*Sup, kid?" Sans asked as he opened the door for you. You hadn't even had to knock, as usual.

"Hey, Shorty!" You replied cheerfully, hugging him as tight as you could. He chuckled, hugging you back... Except he was a lot more gentle. Being a monster and all, you were a total wimp compared to how strong he was. Once you were done hugging Sans,
you dashed into the kitchen to say hello to Papyrus- who hugged you a lot harder. Gaster was just coming down the stairs when he noticed you, sneering. "*Pet."

Gritting your teeth, you stepped up to him. For Toriel. For Toriel. For Toriel, you chanted, which didn't really help much. "Gaster, I need to talk to you." You said as neutrally as could be managed. He raised an eyebone, but chuckled and nodded.
"*Come with me~" he purred, leading you back upstairs and into his room.

You glanced back at Sans, signing 'I'll explain later' at him. He looked uncertain, but nodded his 'okay'. You really didn't want to go into Gaster's room, but it did need to be private and... well... you always had been curious. Even SANS let
you in his room now, as long as you had permission. Gaster walked in behind you, shutting the door as you sat on the edge of his bed nervously. This was a bad idea. Ho BOY, this was a bad idea. You repeated in your mind as he sat in his desk
chair with a smirk that told you it was too late to pretend this never happened. "*Well, pet~? I'm listening."

Don't stab a pencil into his eye socket. Don't do it, (y/n). It's a bad idea. Don't!

Pushing the murderous thoughts aside, you tried to figure out a way to explain to Gaster you needed to keep an eye on him. "Er, okay, let's see... Goatmom is worried about you. She told me to make sure you stay out of trouble." His smirk disappeared.
"*She what. She wants you to be my babysitter? HA! HA! I don't think so, Babybones." He'd been leaning back lazily while talking, until he'd called you Babybones. You blinked for an instant and he was right in front of
you, eye-to-eye, and the gaze that met yours was cold and calculating. You could feel your fears crawling on your back.

"*Listen to me, pet. You can hang out with me and babysit me all you want. But if you do, you're going to have to do what I say. As I've told you before; a human is fragile. If they don't have a monster to protect them... they get hurt."
The way he said it, no teasing, no hint of smugness. It was chilling. It was a threat, clear as day, and the way his voice was lazily drawling it out, as if it was just a comment on the weather, made it worse. For a moment, all you did was stare.
Why was it you who ended up in situations like this?

But then, you realized. This was the perfect set up for a novel. A promise, a jerk, a best friend? Oh, something amazingly epic was bound to happen soon, and you were going to be part of it! The fear was pushed aside and you nodded determinedly.
"Fine." One blink later and he was back in his chair, smirking and winking at you like nothing had happened.

Yet another thing he and Sans were similar in; you'd been threatened by the other skelebro before, and the styles in which the two went about it were so alike it was almost copying.

"*Good girl." He praised gleefully, ruffling your head like a cat's. "*Now, go play with your little friends, and we'll go to the mall afterwards."

It took you the entire trip down the stairs to realize what he'd said and the implications of it.

How did he know you were going to the mall?! (And a quieter voice asked if this counted as hanging out, babysitting, or a date. One of which was so traumatizing you suppressed the memory of thinking it.)

"*Soooo..."

"*Toriel made me promise to keep him out of trouble." You explained simply as the two of you sat tinkering with the Magic Blasters. Sans' sockets widened for a moment before he laughed. "*Oooh man, yeah. I understand that completely. So what
happened up there?" You debated the pros and cons of telling him the truth. (Pro: letting Sans dust him would probably void the promise. Con: you would be breaking the promise letting Sans dust him.) "I told him about the promise and convinced him
to let me. It wasn't too hard; I just said he could call me pet once a day with no retaliation." That was actually true, you had said that before leaving. He wouldn't let you leave until you agreed, the prick.

Sans huffed, but said nothing more on the subject. He was protective of you, but he also knew you could handle yourself. Besides, confronting his older brother was too much work. "*Okay, Magic Blaster Prototype, Test #3345. Ready?"

"Ready!" You replied, giving a thumbs up to the recording video. After 3345 tries, you two still hadn't given up... or, more accurately, you hadn't let Sans give up. Slowly, carefully, you put on the black, fingerless gloves with the glowing red
circles. It reminded you of Iron Man's gauntlets, which were cool but you were more a fan of Spider-Man. "*And, in three... two..."

"One!" A soft 'fzzt' was the only audible clue to the fact that you had fired. The visible clue was a lot easier to see. For a moment, you and Sans exchanged looks from each other, to the gloves, to the two weapons you had formed from the hard
light coming out of them. "*It... It wor-"

"SANS WE DID IT!" You had shut off the MB (whose name wasn't really accurate since it didn't actually 'blast' anything) and jumped around, practically glomping him to the floor. "It works! It works! Sans, you're the smartest person I've ever met!"
He got caught up in your enthusiasm, grinding wider and laughing quietly as he tried not to get dusted. "*Er- (y-y/n), you're crushing my ribs." Blushing, you quickly rolled off him. "Oh! I'm sorry! I forgot." You covered your face in embarrassment,
always a little shy after having burst out like a five year old on occasions like these.

"*Nah, it's fine. I... think it's cute." As much as it would have been a game-changer for you to hear what he'd said, you couldn't make out what Sans told you, because the last sentence was mumbled under his breath. Still, his assurance was enough
to forget about the excitement and get back to work. After all, you needed to find the bugs in the program before you actually used it for anything!

You did truly wonder what he'd said. When you asked, he replied with "*Oh, I said I think it's cool." Something about it struck you as off, but Sans didnt betray any hints that he might have been lying.

... You'd forgotten that Gaster was going with you to the mall. Agh, and the day had been going so well! "*Ready to go, pet?" You opened your mouth to reply in some snarky way, but he teleported you before you could. "*Come on." Not even waiting
for you to catch your breath, the tall monster grabbed your wrist and practically dragged you away from the building and into the back alleys.

"Hey! Wait, I thought we were going inside?" You asked, confused and trying to figure out what was going on. Gaster just laughed and ignored you.

While he dragged you around, you had time to think. It was weird that he so suddenly was bringing you around to some place you assumed was secret. It was like you two had gone from absolute enemies to partners in crime almost instantaneously. "Where
are we going?" You finally asked, trying to figure it out.

"*You want to keep me out of trouble, right? Well, if that's the case then you have to come with me everywhere." Well, that answers THAT question. He's using this as an excuse to make you do a ton of crap you would never agree to otherwise.
"*And that includes hanging out with my friends." Case in point.

"And what are these 'friends' of yours' opinions on humans?"

Gaster only turned his head just enough to see you out of the corner of his eye with a smirk, like all the cool villains and anti-heroes did in anime. "*They make great pets."

Oh HECK NO. "I am NOT going into one of those weird clubs for furries!" You tried to break his grip, but... well, refer to earlier, the hug with Sans. Monsters are freaky strong. "*Relax, Babybones. It's not like that. You'll be the only
human there." Like THAT'S comforting. "*And if you aren't my pet, then you're part of the game, and I doubt you want to be part of the game." Yes. Because THAT'S even MORE comforting. "Just where are we going?!" You asked,
a little horrified, even without understanding. Gaster rolled his eyes as you came to a stop in front of a guarded door. "*The Monster Insurrection Club, duh."

Oh. No big deal then.

You were just about to walk into a warehouse full of monsters who want to enslave and/or destroy and/or imprison every human on the planet.

WHY did you make that promise?
