The News

You and Sans woke up from your nap from Papyrus banging on Sans' door.

"SANS! DINNER IS READY AND I CAN'T FIND ARIE, HAVE YOU SEEN HIM?"

Sans looks at you as you quietly try to get dressed.

"i haven't seen her―him i meant him." Sans corrects himself as you give him a glare.

"I'M GOING TO CHECK TO SEE IF HE IS WHERE WE TRAIN IN THE FOREST!"

Papyrus stomps off and you listen to the front door closing and look back at Sans.

"You need to be careful when you address me as 'her' on accident, otherwise someone might start suspecting things."

"i know, i'm still getting over the fact that you're a human and not a guy." Sans apologizes.

"It's okay Sans. I just hope you can keep this a secret since I basically gambled my whole life of showing you that i'm a human."

          You finished putting on the rest of your disguise and was about to put on your mask but Sans stopped you to gazed at your pretty face.

"i wish i could look at your face all day." He sighs.

"But you do that already." I say.

"i meant while your face isn't covered." Sans says as he pulls you in for a hug which lifted you off the ground.

          You could tell that Sans was trying his best to be gentle with you as if you were a glass doll that would break at the slightest touch. You wrap your arms around his neck as he lets out a sigh.

"You okay Sans?" I ask concerned.

"can i ask you something?"

He releases you from the hug with his hands resting on your hips.

"will you be my girlfriend?" He says blushing.

you smile at Sans' request.

"I thought you'd never ask, but are we going to keep this a secret or let everyone know about this?" I ask.

"i want everyone to know that you belong to me and that you are mine." He says with a slight growl in his voice.

"Possessive are we?" I tease.

"just a bit."

"Right, just a bit." I say sarcastically.

          You both walk down stairs to see what Papyrus had made for dinner. It was another one of his attempts of making spaghetti again, you couldn't figure out how Papyrus was able to do very difficult meals and was not able to make one of the most simple meals such as spaghetti. The noodles were over cooked and the sauce looked like it was burnt and had a very gooey form. Sans was gagging from the smell as you were still thinking how Papyrus could've over think the process of an easily cooked meal.

"ugh, i haven't seen Papyrus cook this bad for years. lets go to Grillby's." Says Sans.

"But what about Papyrus? I don't want to hurt his feelings."

"don't worry Papyrus is used to my criticism, he knows if he's messed up or not."

          Sans convinces you as you walk to Grillby's together, walking closer to each other than normally. I guess you accepted the fact that you want to be with Sans and you don't have to hide it anymore which is why you're walking close to him. You walk in and see Grillby's just as crowded as usual and walk over to the bar and sit down. Grillby was exceptionally busy tonight as he rushes in and out through the back with plates of food. He comes out with three plates of burgers and notices the two of you.
