(Sans x Reader) When Two Souls Meet

Duty Calls

Your Perspective

You smile as you push the door to Grillby's open, its attached bell cheerfully signaling your presence. The buzz of conversation in the room pauses briefly, just long enough for the regulars to call out greetings to you.

"Hey, (Y/N)!"

"How's it goin,' (Y/N)?"

"Hi, guys!" you call back, giving the monsters a small wave. After a few days of working at Grillby's, you're starting to become more comfortable around the customers. In fact, you're actually starting to gain a few new friends—you're not nearly as popular as Sans, but your music is quickly turning you into a close second.

"Yo! Miss (Y/N)!" a young monster hollers, bouncing excitedly over to you. "You're going to play again, right?"

You crouch down so that you're at their eye level, a warm grin lighting up your face at their enthusiasm. This little armless reptilian monster has come to all six of your mini-concerts so far, and has quickly become one of your biggest fans. (Yes, as amazing and unbelievable as it is... you have fans. Of the domestic sort. It's not like you're a big-shot, or anything.) He's also one of Frisk's friends, and you often see the two of them playing in the snow together. If you remember correctly, Frisk introduced him to you as monster kid, or MK.

"I sure am," you chirp, your eyes following their energetically bobbing frame. "Let me guess—you have a request for me, don't you?"

"Yeah, that's right!" he exclaims, his tail waving happily in the air behind him. Then he hesitates, a more uncertain expression taking the place of his usually overconfident one. "Uh... that's okay, right?"

"Of course."

MK beams at you and scurries away, back to the table that's occupied by two larger reptilian monsters—one pink, and one orange, both equally armless. His parents, you assume. He grabs something that had been laying on top of it with his mouth before hurrying back over to you. Stars sparkle in his eyes as he anxiously waits for you to take it.

"Is this sheet music?" you ask, gently taking it from him and looking it over.

You can't help but grimace as you catch sight of the front cover. It's neon pink, and it features a very narcissistic looking, humanoid robot. He's striking a ridiculous pose, lounging on top of a grand piano with a red rose held expertly between his teeth. Between the gaudy pink getup (why on Earth is he wearing heels?!) and that insufferable smirk on his face, you almost feel as if you're holding something a lot more... adult... than a scorebook. You quickly leaf through it, feeling a little relieved when you find musical notes on its pages.

"Yeah!" MK affirms, completely missing the disgust that originally flashed across your face. "It's the piano music for Mettaton's hit songs. I really like his song 'Haven't you Noticed I'm a Star.' It's on page 10. Can you play it? Pleeease?"

You turn to the song MK requested, scanning the page. It doesn't look too difficult, but it's not too simple, either—right in your comfort zone. From what you're limited grasp of sight reading can make out, it has a bit of a pop flair to it. You're not too enthused by the accompanying picture, though. This 'Mettaton' person is striking an extremely corny, and yet somehow seductive, pose. For some reason, it reminds you (and not of a good way) of a certain celebrity from the surface. You're not going to turn the little dinosaur down, though. He's just too adorable in that oversized yellow and brown striped sweater of his.

"Sure, MK, I'd love to play it for you," you say, forcing down the urge to find the nearest trashcan. "It'll take me some time to learn, but I'll see what I can do. Uh... should I make a copy of it, or...?"
