------------------

Ever since you had to move out of Toriels, you've been rather lonely, you missed the smell of pie greeting you every morning.

But, you had to move out because frisk insisted that their boyfriend Mk should live with them now.

Toriel didn't want you to leave, but you knew you had to or else it would be to crowded.

You lived in hotlands now, Alphys was your dorky neighbor along with mettaton.

You were kind of jealous, you wanted an awesome robot to live with you too.

So, today you decided to go and pay Alphys a visit, maybe she could make you a roommate.

--------------

"Heya Alphys, what cha up to?" You ask her, entering her lab.

She blushed and dropped her pen. "O-oh y-y-y/n! I'm sorry I didn't see y-you t-there!"

You laughed a little. "Its okay Alphys I didn't mean to scare you. But I did come to ask if you could make me something?"

She adjusts her glasses and hopped of her chair. "Oh! Sure! What is it you n-need?"

You sat in the Spinny chair across from her desk. "Well.. Since my house is boring and too quiet.. I was wondering if you could make me.. Um.. Well a robo roommate?"

She put her claw to her chin in thought, then she grabbed a clipboard. "S-sure I can! Anything specific?"

"Well I was thinking maybe one like sans? You know before.." You wiped a tear away.

Alphys pat your shoulder. "I-i understand.. S-sure, it won't be t-totally the same as him. But I can try for you." She smiled sadly.

You gave her a saddened smile then hugged the nervous lizard.

"Thank you Alphys."

"Y-you're welcome y/n."

----------×Time skip×-----------

You just sat on your leather couch, waiting and watching the phone. Waiting for it to ring.

It had been a few weeks, maybe two? Since you've last seen Alphys.

She said that she'd call you as soon as robo sans would be done.

You were very impatient.. You just wanted your sansy back.

Because of what happened to him, papyrus had to live with undyne, he couldn't afford the house anymore.

Grillby was even upset over it, he had lost his best friend and best customer, who still hadn't paid his tab.

The day before he died, he had taken you to waterfall for your first date.

You were so happy, but.. You wished you had kissed him before he had turned to dust.. Thanks to flowey..

You hated him so much.. But your phone rang and you excitedly grabbed it.

"Hello?"

"Y/n! Come quick! He's finished!"

You smiled like a dork and slammed the phone down and ran out the door, not bothering to lock in or shut the door.

----------------

Alphys sat at her work bench with a giddy smile, something large was sitting on said workbench, with a large tarp thrown over it.

"Is he done!?" You smiled hopping up and down like a kid in a candy store.

Alphys giggled. "Y-yes you w-weirdo." She pulled the tarp off revealing a robotic version of sans.

It was uncanny at how much it looked like him, just a few changes.

He was dressed in a suit, dark blue vest, dark blue pants, a light blue work shirt under the vest, and a golden wrist watch around his wrist, and lastly two dress shoes.

He was very steampunk looking.

(Pic above if its there! And btw I freaking love steampunk!)

You smiled. "Turn him on!"

Alphys looked at you funny, as if judging you.

You blushed. "Not like that! I mean power him on!"

She giggled and flipped the switch on the back of his head, powering him on, his eyes came to life.

Sparking blue for a moment before turning back to those beautiful ivory eye lights you loved.

You smiled and hugged Alphys again. "Oh alphys thank you! Thank you!"

She smiled and shrugged. "A-anytime!"

You turned to Sans and smiled, tears falling down your face. "Oh sans, I know you're not the real you, but..  I just had to have you back."

He stared at you for a moment before gently hugging you, trying not to crush you.

You smiled even more, blushing to. You hugged him back.

No words needed to be said, you held hands with him, as you both walked out of the lab.

You made a mental note to give alphys some of your manga later.

------------------

Sans 2.0 acted exactly like the old Sans did, almost as if he had all of the memory's of the old Sans.

He was a complete gentleman as well, you knew alphys had added a few quirks.

Sans sat next to you, his arm around you, you snuggled into his chest. "Ah sansy, I'm so glad to have you back. You have no idea how much I missed you."

He chuckled. "I wasn't gone very long y/n, and besides I missed you too." He snuggled into your neck.

You blushed even more.

-------------------------

You and Sans were officially together now, he didn't want to leave the house however, he just wanted to be with you all he could.

But, one thing you noticed.. He's gotten more.. Possessive.. Did alphys add a yandere mode? If so did you accidentally flip its switch?

You didn't know, but last time alphys called you, he shot the phone with a bullet from his finger tip.

"Sansy, is everything okay?"

He nodded staring blankly at his stained hands as you did minor maintenance on the back of his head, he had glitched a few times this week.

"You sure? You keep glaring at my online guy friends, and you almost broke the pizza guys hand! I know you're protective over me but.. This is insane!"

He suddenly stood up and his gears turned, making his body turn your way. "Insane? Insane!? I'll show you what's insane!" He suddenly pinned you to the couch, his metal strength forcing you to stay in place.

"S-sansy! Y--youre scaring me!"

He kept silent and pressed his teeth to your lips, it was gentle until his left hand ran down your cheek, some type of liquid running down his hand.

"S-sansy w-what is that?"

He pulled away and chuckled.

"Oh you know flowey? And Alphys? Well... They're gone now. Its just you and me.~"

End...? There may be a part 2 in the future idk. I'm tired this was a lot to write..--__--
