Sans had been pretty happy ever since he had heard the voice behind the door.

He felt more energetic when he woke up, and he even stopped having those horrifying nightmares that constantly reminded him why he had ran away to the ruins. And he stopped throwing away half of his meals, instead, he actually ate the required amount for a skeleton to stay inside of good health. He was happy for once, he had a new friend!

And that morning he saw the 7th human child that had fallen.

They were facing the horrid monster named Flowey, surrounded by 'friendliness' pellets. Sans knew Flowey called them that when he tried to trick Sans, pretending to be his brother. Sure, he had the memories of Gaster, but Sans knew that wasn't his younger sibling.

Gaster had died, and he had accepted that.

This stupid flower tried to play with his emotions, which he discovered and managed to fight back. So, Sans was rather angry when he saw the flower about to kill the fallen child.

"You get away from the kid you awful flower!" Sans yelled, throwing a bone attack at Flowey.

The black flower yelled as the bones hit him, sending him flying to god knows where. The brown haired child looked over at Sans, sighing with relief.

They were wearing a blue sweater with purple stripes on it, along with blue shorts and brown shoes. Their eyes were closed, but they seemed to be able to see just fine.

"Heya Kiddo," Sans said, sticking out his hand, "Nice to meet ya. Sorry about that flower, he's got no soul. Names Sans, how about you?"

"Frisk," The child replied, smiling up at him, "Thank you Sans!"

"C'mon Kiddo, I'll show you around the ruins," Sans said, intertwining his fingers with the humans, "And don't let that flower decide how you think of monsters. We're all not bad, just some of us."

Sans led her to the large room with light shining down from above, leading her to the doors puzzle.

"Monsters are kinda weird, instead of setting up traps we set up puzzles to trap humans instead," Sans said, "This is one of the many puzzles you'll see, kiddo. Don't get puzzled trying to solve them, I'll teach ya how."

Sans stepped on a few buttons before the door clicked open, grabbing Frisk's hand once more.

"They aren't too difficult. For the next puzzle, I marked them for ya, just gotta flip the switches."

Sans led her to the next room, pushing his hands together and letting the baggy sleeves of his robe connect, smiling at Frisk.

"Go ahead, I'm sure you'll figure this out," He said reassuringly.

The runaway Prince watched as the human child flipped the first switch before they progressed over a bridge, flipping the second labeled one.

"Nice kid," Sans said, grasping her hand once more, "I think the next puzzle is too dangerous for you to solve on your own, so just follow me."

When her gaze landed on the old spikes she froze, her face filling with fear. She didn't want to die, not by this.

"Sans," She muttered, gripping onto his dark blue robe, "I'm scared, I don't want to walk through that..."

"Here kid," Sans said, crouching down, "Climb onto my back, I'll give you a piggy back ride."

Frisk nodded before climbing onto his back, his hoisting her up.

She was shivering as he slowly, yet calmly made his way through some of the spikes, her holding back tears as they reached the halfway point. Sans sensed this and quickly came up with a pun to take her mind off of it.

"Hey, are you sure you aren't a skeleton?" He asked her, "Because us skeletons weigh a ton, a skele-ton."

Frisk giggled at the pun, distracting her enough so Sans could quickly walk the rest of the way through the deadly trap.

"There we go kiddo," Sans said, "See, no problem, I have you. I'll keep you safe here."

"Thanks Sans," Frisk said, climbing off of his back while he crouched down.

"Now," Sans said, rubbing the top of her head, "Forgive me for this, but it's necessary."

And with that, he rushed off down the hall, disappearing from view.

"Wait, Sans!" Frisk yelled, but Sans had already disappeared down the hall, escaping her sight.

"Oh boy..." She muttered, hugging her arms to her chest as she made her way towards where he had ran off to, keeping am eye out for Sans.

She passed by a large conveniently shaped lamp, stopping when she saw Sans peak out from behind it.

"Kid, don't worry," He said, leaning against it, "I didn't leave you, I have a soul. But there was a reason I had to do this."

"There was?" Frisk asked, looking up at him.

"Sorry kiddo," Sans said, kneeling down and ruffling up her brown hair, "But I have to take care of some things, you'll have to stay here for a bit. But here, I have a phone you can use to contact me in case of emergency."

"That's okay Sans!" She said, taking the phone from him, "I can wait here for a bit."

"Thanks a bunch kid," He said, standing up, "Be back in a few."

And with that, he walked off, leaving Frisk alone.
