Sansational! (Sans X Reader)

The Tsun-tsuns (Underfell!Sans x Tsundere!Reader)

(You've experienced a Yandere!Reader. Now, I present you, Tsundere!Reader!*The first request I've ever gotten... I hope I don't disappoint.)

(also probably OOC or something...this is one hella challenge)(he'll probably sound like Karkat Vantas im sorry)

.....

Sans hid behind a tree, the sight of you brought anxiety to him. He fidgets as he peeks out to your direction.

You were currently speaking with Undyne.

"H-Hey Undyne, by any chance...did Sans come by here? N-NOT LIKE I WANTED TO SEE HIM OR ANYTHING." You were putting up a tough front, arms crossed and blushing slightly.

Sans was supposed to go and hang with you, but now, he's having second thoughts. For he was also blushing red now. Both of you wanted to talk with each other... It made Sans' inside feel all... warm? Nah...It couldn't be... He thought.

Undyne suddenly pointed her spear to the tree Sans was hiding in. This caused the skeleton to panic and skedaddle out of there.

Unfortunately, he failed miserably. His panicked movements caused him to fall, face to the ground.

.....

You checked behind the tree Undyne pointed at and saw Sans...planking? Was he sleeping? Hmm, probably not, we're talking about THIS Sans. He'd have a reason for this. You thought.

"H-Hey Sans!" Shoot did you just stutter- NO. STOP IT ______. ACT TOUGH.

Sans heard you and got up, arms crossed. "What the hell, ______? I was resting!" You swore that beside his usual angry face, there was a sweat-drop, building up each second he talked to you.

"Excuse me? Does it look like I'd disturb you for no apparent reason?" He didn't have to talk to you so harshfully... You thought, fingers gripping on your sweaty palms.

"As far as I can see, you're already disturbing me for no damn reason at all." Sans shouted, but immediately regretted. He covered his mouth with his hands, looking terrified to what he'd just said.

You were there, face contorted to both anger and sadness. You yourself can't tell. Why was he so mean to you?

"Is it such a f*cking sin to talk to my bestfriend, the only f*cking skeleton I could actually talk to in this god-forsakened place?" I hate him! I hate him! You tell yourself, tears already falling like niagra falls, but you know that you can never fully hate this skeleton. He was your only friend- no. Screw that, you love him from the depths of your lonely heart. Even if he acted like you were a nuisance to him, you knew that there was a bond between you. A bond of love and hate.

You turned from him and ran far into an alley, leaving him dumbfounded and teary-eyed as well.

...

Sans felt bad. He didn't mean to hurt you. For f*ck's sake, he doesn't know how to deal with these kinds of situations.

Actually.. Why is he feeling bad? This kind of thing was supposed to be normal between you both. The usual at each other's throat thing.. The usual banters.. What changed?

He clutched his sweater. He doesn't have a heart, but why is it as if he has a real beating one, aching because of what just happened?

"Ugh, this is so disgusting." He said to himself, teeth clenching loudly. Damn it.. Just go after her, you dummy.

So he did. He ran after the direction you went in and deliberately checked each alley.

Soon, he found you. Crawled up on one corner, turned to the wall. He could hear your silent weeping from afar. He's done it this time.

"Look- er.. Look... I didn't mean to... hurt you.. It's just- I just-"

"Do you hate me?" You ask, hiding your tears by wiping them off.

"I- Of course, I don't! Y-You have no idea. How much I- Argh.. I F*CKING LIKE YOU MORE THAN YOU THINK, YOU DUMBF*CK." He was shaking, probably in embarrassment. This ultimately startled you. You didn't think he would confess now... Heck you didn't think he'd confess at all. You sincerely thought he only thought of you as an annoying friend.

You gained composure and approached him. Sans didn't look at you and dodged your stare at his pupils.

You slapped him hard.

"WHAT THE F*CK, WOMAN!?" You guessed that it hurt pretty badly. You semi-intended it, but you were also sorry for him.

Grabbing him by the collar of his sweater jacket, you kissed him passionately and deeply. You don't even care what will happen next. You just want to make this moment yours.

Sans flushed red, unable to speak in amazement of your audacious move. Later recovering from the sudden shock, he just held your hand tightly and dragged you to walk. Although, both of you were just walking aimlessly.

"Hey."

"W-What?"

"I love you too, you asshole."
