Sans had been talking to the mysterious voice for over a year now they had been mostly telling jokes but also talking to each other about what they do. Sans found out that the woman was the caretaker of the ruins and he told her that he was a sentry. A few weeks went past and neither would want to admit it but they were rather fond of each other despite not having seen each others faces before. But one day the woman wasn't laughing as much as she useually would.

"Hey what's wrong? Your not laughing as much as ya usually would" The woman sighed.

"can you promise me something?" Now Sans never liked making promise but he felt something with this woman so after a moment he smiled.

"yeah sure what is it?" After a moment of silence the voice came back.

"if a human ever comes through these doors can you watch over them and make sure they are safe?" Sans was shocked but agreed.

"yeah sure no problem" the voice sighed and the jokes then started up again. Severel weeks Sans went on sentry duty when he saw a small girl at the entrance to the door. The girl was a human she had short brown hair and pale skin she was wearing a bue and purple striped jumper with blue denim shorts. The girl seememed pretty banged up with a plaster or two on her legs. She carried a stick with her but not in a threatining way but she almost held it as some form of protection. Sans smiled and rembered the womans words walking up to the kid. "hey human don't ya know how to greet a new friend?" He stuck out his hand and the kid took it a farting noise erupted the kid smiled and began lauging as Sans smiled saying. "the whole whoopie cushion in the hand trick works every time"

Time skip because its not important to story

Sans couldn't believe it the little kid that small scared kid had managed to break down the barrier but for some reason he had a idea that the little weed had a part in it, he would have to talk to the kid about it later. For now he had to meet someone he had finally met the person who the voice belonged to. Her name was Toriel as in Queen Toriel. Sans couldn't believe that he had been talking to royalty all these years. The first time he saw her he had to make sure that he didn't drop his jaw. Sans had never seen someone so beautiful before when she looked towards him he could feel the blue blush creep across his face. By now Sans had walked to the entrance of the barrier where the spell would be lifted and he would revert back to his natural form stepping out of the mountaine a golden spiral encircled him. When it left Sans looked down and saw that he was back to normal he was a short pale human. His hair was short and spikey he wore the same outfit as before but he still had his striking blue eyes. Looking around the other rare people were turning back to normal Papyrus was tall and thin with short white hair and orange eyes. Sans had examined all his friends when a tug on his jacket made him look down there was Frisk, the human child, kneeling down he smiled.

"hey kiddo what's up?" Frisk smiled and pointed Sans followed Frisk's point and the sight nearly made his heart stop. Toriel had just been turned back to normal he sleek white hair landing on her shoulders she was wearing a long purple dress with the underground symbol and a light purple silk ribbon around her waist. Her face was smooth with porceline white skin her blue eyes shone like dimonds and her rosy red lips complemented her as well. Sans stared with his mouth wide open Mettaton saw this and walked up to him jokingly saying.

"oh please put your tounge back in your mouth darling" Sans shuck his head a blue blush creeping across his face as he pulled his hood over his head. Mettaton shuckled. "why don't you just go and talk to her darling. You both said you've been talking for a year now, right?" Sans looked at Mettaton and nodded.

"your right Mettaton I'm gonna go talk to her right now" Sans did not move he stayed frozen in place. Frisk smiled and pushed Sans making him stumble into Torile. "oh my goodness i-I'm so sorry" Toriel chuckled.

"do not worry about it Sans. It was my fault I wasn't looking where I was going. Have you seen Frisk by any chance?" Sans smiled and used his powers to make Frisk float towards them.

"here's the little bundle of energy" Toriel chuckled and took Frisk's hand.

"it was very nice to meet you again Sans" Sans smiled and looked down noticing that Toriel was gonna leave Sans looked up saying.

"um, hey, I was wondering would you like to go grab a bite some time?" Toriel smiled.

"I would like that very much Sans"
