Papyrus frowned as he watched his brother happily bounce into the house.
Sans had been acting oddly for a full three weeks now; eagerly going to do the sentry job Papyrus had assigned him and coming home with a larger-than-average grin. Today Sans seemed especially cheerful, and Papyrus wanted to know why.
"Hey Pap" Sans greeted as he hopped by, "I'm gonna go take a nap before I go to my next job, kay?"
"Papyrus eyed his brother suspiciously, Sans didn't notice. Yep. Something was up.
The next day, Papyrus went to wake Sans as per usual, only to find that he'd already left.
"What's going on?" Papyrus mused as he speed walked to the gate, "Why would that lazybones ever wake up early of his own accord?"
As he neared his destination, Papyrus heard his brother's voice getting louder and louder; Sans was talking to himself.
"A perfect opportunity" Papyrus grinned, jumping to hide in a close by bush.
"Okay, okay, okay" Sans said to himself, pacing pacing back and forward, "so it could have been a joke like any other, or it could have actually been...eeeeeeh."
Papyrus was facing Sans' back, but he noticed a light blue glow around Sans' face signifying that he was blushing. What made Sans like this?
"But whatever the case" Sans hurriedly continued, shaking his head in an attempt to get rid of his blush, "just act natural, you'll be fine."
Papyrus wasn't sure what the motivational speech was about, but it was pretty obvious that his brother was nervous about something.
Papyrus was about to stand and see what Sans was worried about, but a light tapping on the door interrupted him before he could move.
"Knock knock" a woman called.
Papyrus watched as Sans jumped slightly at hearing her voice before blushing, then shaking his head to remove the blush again and leaning against the door, attempting to be confident, "who's there?"
"Adore" the woman replied.
"Adore who?" now that Papyrus could see Sans' face, he could see that his brother was grinning.
"Adore is between us, open it up!" the woman giggled.
Oh no.
"Knock knock" it was Sans who asked this time.
"Who's there?"
"Doris."
"Doris who?"
"Doris locked, that's why I'm knocking" Sans grinned, "come on Tori, you know I should be dooring the door ones. You're not the one who's trying to open it."
Papyrus wanted to die. He had to listen to them share jokes. And there was no escape otherwise Sans would notice him.
"It's not like you to make rules" the woman Papyrus now knew as Tori teased.
"It's not like you to flirt with me" Sans shot back with a blush, Papyrus' jaw dropped.
"Well, I guess everyone's been acting differently lately" Tori giggled.
"Definitely not complaining" Sans chuckled as his blush glowed.
"Neither am I" Tori replied, "are you a banana?"
"Why do you ask?" Sans wondered.
"Because I find you a-peeling."
"Okay, okay, I've got one, guess what my favorite part of a game is" Sans grinned.
"Uh...the boss battle?" Tori attempted.
"Nope. The tutoriel."
Papyrus then realized that 'Tori' might just be a nickname, and he guessed that 'Toriel' was her full name.
Toriel giggled, "well, you know how I've always wanted to be a teacher?"
"Yeah?" Sans nodded.
"Well, teachers have this certain font that they know their students hate. Personally it's my favorite" Toriel continued.
"Which font is it?"
"Comic Sans" Toriel giggled.
Papyrus felt himself dying inside. Sure Sans and his mysterious girlfriend were cute, but Papyrus didn't want to deal with any more of their terrible puns.
"Huh?" Sans blinked.
"What was that?" Toriel asked, "is someone else there with you?"
"No" Sans frowned.
Apparently Papyrus wasn't dying inside as much as he was groaning. Loudly.
Sans walked up to the bush where Papyrus was hidden and instantly recognized his brother.
"Papyrus?" Sans blinked.
"Papyrus?" Toriel repeated, "wait, you mean your brother?"
"The one and only" Sans replied.
"As much as I'm honored to know that you told your girlfriend about me-" Papyrus found himself cut off.
"Girlfriend?!" Sans let out an embarrassed squeak and glowed blue.
"O-oh, no, I'm not his girlfriend" Toriel denied.
"You're not?" Papyrus blinked.
"Not yet" Sans mumbled, forgetting that Papyrus was close enough to hear.
"What? What's so funny?" Toriel questioned when she heard Papyrus snickering.
"H-he said-" Papyrus was about to quote his older brother's words, but Sans tackled him. Sans' reaction only made Papyrus laugh harder.
"What? What is it?!" Toriel was obviously feeling left out of the loop.
Papyrus wrestled with Sans a little before continuing, "When you said you weren't his girlfriend, Sans-"
"SAID NOTHING!" Sans yelled over his brother.
There was a loud creak and suddenly, the gate opened outwards, making the brothers freeze in surprise.
"T-Tori?" Sans' jaw dropped, watching as a tall figure exited the gate.
"Yes?" Toriel's familiar voice replied.
Sans didn't know what he imagined her to look like, but now he couldn't see her looking any other way, "holy shit marry me."
"Wh-what?!" Toriel blushed.
Papyrus burst out laughing.
