{Frisk's POV}
"Wow... the crystals are so blue... it's almost as pretty as Sans' eyes..." I thought, fingering the blue echo flower charm Sans had gotten me on my 2nd anniversary of being SAVED from my genocidal ways by Chara.
I can still remember exactly what he had said while putting it on my neck. 'HUMAN, THANK YOU FOR BEING A GREAT FRIEND! PLEASE, TAKE THIS AS MY OFFER OF... LOVE BETWEEN FRIENDS!' and after that, with a bright blueberry blush, he had kissed me on the cheek. I could still feel the little shock of magic that had been passed from his teeth to my cheek.
"You've been blushing a lot lately Frisk. Is there something, or someONE on your mind?" Chara asked from next to me, still looking at the whispering Echo Flowers in front of us. Alphys and Undyne looked over at me, taking in my flustered face.
I jumped up a little, a red blush covering my face, "Oh! Uh n-nothing! N-no one!" I stammered, internally scolding myself for thinking about the smiling shi- crapbag's brother that way.
"Are you sure Punk? Chara's right, you do that more often then Undyne does." Alyphs pointed out, smirking as both the fish scientist and the golden-eyed human immediately started blushing and stammering out broken retorts.
Both Alyphs and Chara shared an unusually evil glance before asking in unison "Don't you also do it when Sans is next to you? Or when he's in your line of sight?"
"Y-yeah, you a-always d-do that when we t-talk about him t-too, like as o-of now." Undyne added
"Wh-what! Th-h-hats not true... is it? W-wait a second! What are you implying?"
"WE ARE IMPLYING THAT YOU LOVE HIM!" Chara, Alphys, and surprisingly Undyne yelled.
"W-what?! That's bonkers!"
"Oh come on Frisk, you can't fool me! We see how you look at him! Own up to it!"
Undyne quickly pulled out her cellphone and pressed a button, starting up a song.
[START SONG IF YOU WANT TO]
I started singing,
"If there's a prize for rotten judgement, I guess I've already won that. No man is worth the aggravation, that's ancient history, been there done that."
Chara, Alphys, and Undyne retorted with "Who you think you kiddin'? He's the earth and heaven to you! Try to keep it hidden, honey we can see right through you. Girl you can't conceal it, we know how you feeling, who you thinking o-of!" , Undyne pulled out yet another contraption, which showed Sans smiling down on me, and I barely caught myself before smiling.
"Oh, no chance, no way, I won't say it no-no."
"You swoon, you sigh, why deny it oh-oh?" They sang, obviously getting fed up with my denial.
"It's too cliche, I won't say I'm in love..." I kept going, walking towards one of the glowing blue rivers Waterfall had to offer, with the others following me.
"I thought my heart had learned it's lesson. It feels so good once you start out. My head is screaming 'get a grip girl. Unless you're dying to cry your SOUL out!' oh..."
"You keep on denying, who you are and how you feeling, baby we're not buying, hon we saw you hit the ceiling, face it like a grown-up, when you gonna own up that you got-got-got it bad!" Alphys suplexed a boulder to emphasize how irritated she was.
I started jumping on some on the rocks across the river "Whoa... no chance no way I won't say I'm in love."
I tripped on the last rock... and fell straight into the arms of a Sans statue that Undyne made with her spear magic. This time I couldn't stop myself from smiling a lovestruck smile, and cuddling up against the Sans Statue.
"Give up! Give in!"
"Check the grin, you're in love!" Chara yelled, noticing the cheshire grin on my face.
I shook my head and jumped away from the Sans Statue, "This scene, won't play, I won't say I'm in love~!"
"You're doing flips, read our lips, you're in love!" They said from atop the suplexed boulder.
"You're way off base I won't say it!"
"She won't say it, no!" They looked at each other, and shook their heads in exasperation.
"Get off my case! I won't say it!" I sung, as electric green axes rose from the ground, spelling out 'YOU LOVE HIM'.
"Girl don't be proud, it's okay you're in love..."
I sighed, they were right, I did love him, but "oh~ at least out loud, I won't say I'm in love~."
{Sans POV}
Alphys, Chara, and Undyne sighed out of relief, as Frisk laid in a field of echo flowers, as the flowers repeated her last words. So this is why Alphys wanted me to come!
I blushed as the truth came crashing down. 'She loves me! She loves me back! This is the best day ever! Wait... what am I gonna do now? She doesn't know that I know!' I thought, but I frowned as the last thought came into my head.
An idea popped in my head, it was stupid, but I might as well do it before the chance is gone.
I was filled with DETERMINATION!
{Frisk's POV}
I opened my eyes and stood up from the flowers, brushing my sweater off. Hearing footsteps behind me, I turned around expecting Chara or Alphys to be there to irritate me about my crush on Sans, but I was greeted by two stunning blue eyes with stars in the center.
"Sans! W-what are you doing here?! How long-mmph!"
I was swept into a kiss! And it was the best damn kiss I've ever been given. Well, the only kiss I've ever had. After a long moment, Sans pulled away, with hearts replacing the usual stars in his eyes.
Leaning down towards my ear he whispered, "I love you, will you say it?"
I whispered back "I love you too..."
{Neutral POV}
From behind the boulder, two monsters and a human were watching the whole ordeal.
"S-sans and Frisk make such a-a cute c-couple! T-this is my all-time favorite s-ship!"
"Damn. I never knew Sans had it in him to be so smooth!"
"Yeah, hey Undyne, did you get all of that on tape"
"Y-yes. I-I got a-all of it-t!"
"Good. I vote Alphys as the person who has to tell Pap that his brother and Frisk are dating."
"WHAT!? NO! I VOTE YOU, CHARA! IF YOU HAVEN'T REALIZED HE LIKES YOU! HE'LL BE COOL WITH IT IF YOU TELL HIM!"
"...what?"
"...oh. Heh. Nothing... Undyne help me..."
"Nope. You're o-on your own. Consider this payback for telling Temmie about my Hentai collection."
"What did you say about Papyrus?"
"Um... I LEFT MY STOVE ON!" Alphys cried, sprinting away from the enraged human.
"GET BACK HERE!"
"Ugh... looks like I'm off to tell Papyrus... again."
