Nextale Frisk x Short-sighted!Tsundere!Reader

A/N: new book coming out soon! a little sneak peak: based off the illusions game, Monument Valley! I really love that game, but you know what I realised? the levels are in roman numbers, so you have I, iv, and other stuff. level ten however...level X. now go read the Xtale intro comics on Devianart, and on parts 157 and 158...I think I found something interesting. ANYWAY, ONTO THE STORY!

"God damn them..." you growl, walking through the forest. "Its always me who has to go after the others to fix their mistakes. And then they kick me out, half bleeding to death! What a joke..." you were Y/N L/N, a non-member of the 'enemy' group. After having to fix everyone's mistakes time and time again, you gave up on them, running to the rebel base on Mt Ebott.

You had been walking quite a while, and had made it to the base of the mountain. Only a little more till you reached the top, and to the rebel base. As you took another step, a branch snapped behind you. You froze, nothing came from behind you, so you ran. Suddenly, you tripped on a tree root, and as you fell, another hit your already bleeding ribs. You cough, trying to stand. You slip, and hit your ribs again. "HELP!" you scream. A flash of blue and red appears above you before you pass out.

When you wake up, you still felt sore. You couldn't move, but from what you could see, you were in a medical room. After regaining enough strength, you sat up. There was a figure across the room. You couldn't quite recognise them, since they were meters away, and you would need your glasses to see. But they broke on the way up the mountain.

"W-where am I...?" you whisper, rubbing your bandaged head.

"You're in the Mt Ebott rebel base, Y/N L/N," a male voice says, presumably the person in the corner.

"Who are you?" you ask, a bit more confidently.

"Can't you tell? You're only two meters away,"

"Nope! I'm short-sighted, and my glasses broke on the way to...here," you rub the back of your head sheepishly, looking away.

"I'll remember that. Alphys could probably fix that for you,"

"Ok..." he came a bit closer, sitting beside you. You could tell who it was. Frisk Dreemur, one of the targets for your old alliance group. Since you were head of technology, you came across his profile and grew a huge crush on the 17-year-old. "I'm Frisk by the way,"

"You already know who I am, hehe..."

"Wait here, i'll get Alphys to check your eyes," Frisk oped the door, then yelled, "ALPHYS, GET IN HERE!" before turning back to you. Seconds later, a yellow dino walked in.

"F-Frisk? what I-is it?" she asks.

"Can you give Y/N an eye test?"

"S-sure," Alphys walked to the shelves, rummaging for the equipment. Frisk then came back to you and whispered in your ear:

"I'll be in the hall if you need me," you blush, huffing slightly. He left the room silently, and Alphys turned back to you.

~time skip, a few months later~

You had been with the resistance for a few moths now, and it was a lot better than your old 'friends'. Toriel and Asgore were like parents, Asriel was like a brother, and you had something in common with everyone.

Today, your day off, you were going to have a lazy day and relax. A few days ago, you were classified as a tsundere, according to Alphys and Undyne. Of course, you denied this, and that you liked anyone, so you ignored the pair when they brought it up.

"Y/N, come out!"

"C'mon punk! Just tell us who it is!"

"Though I think we already know~!"

"Guys, leave her alone," Frisk said through the door, and the pair shuffled away. Frisk had also been receiving torment from the two, but not half as bad as your teasing. "Can I come in?"

"Sure," you opened the door, letting Frisk into your relatively clean room. "You wanted to see me?" you tweak your glasses, facing your crush.

"Y-yeah...about something important. I...I like you," he says. "I have for a while now,"

"I-I...uh..."

"Don't worry, Alphys and Undyne told me you're a tsundere, so you're easily flustered~" he says, his head resting on yours. You get lost into his eyes, you could stare at then for days and never get bored. However, you were flustered very easily, so your face was entirely red. You turn away, muttering denial.

"S-shut up," you keep your eyes on the ground, but Frisk hugs you.

"Alright, now listen. Asgore has a job for us. We have to take out Chara, and since you used to work for her, you'd be a great help," he turns your head so you're facing him. "Lets get rid of that bastard,"

"O-ok,"

~time skip~

You were back in your old base, once again. But instead of sitting at your desk, working through glitches, you were crawling through the vents, a laser pen in hand. Despite its size, the laser pen could kill.

You cut the vent floor, landing silently, Frisk following. You then led Frisk to your desk/office, and turned the computer on. The second your finger hit the power button, the door slammed shut. You were grabbed and pulled to the opposite wall before you could even blink.

"Hehehehe...hello there, ol friend. knife to see you~!" Chara giggled, pressing a knife to your neck. "Take one more step Frisk, and the girl gets it," she dug the blade into your neck, beads of blood dripping onto your collar.

"Let my girlfriend go, demon," Frisk seethed. You blushed, but your vision blurred slightly when Chara threw your glasses to the floor.

"Step forward, take her...take her dead body," Chara pressed harder, and you whimpered slightly. You knew what Chara was capable of.

"F-Frisk please...j-just go. I..." you smiled, lurching forward and catching Chara off by surprise. her head hit the ground, and you used the laser pen to shoot through her head. "Told you attacking her distracted would work, and I need new glasses,"

"You do realise what I said...right?" he advanced on you, enough for you to touch the wall. "I like you, y'know,"

"I....uh...heh...." you blushed, looking away. He pulled you into a short and sweet kiss, before taking to back to the hole in the vent.

~time skip~

"Alphys!"

"Yeah Y/N?"

"What to you have to say about this?"

"Is it a crime to write fanfiction?"

"If it involves me and Frisk, yes!"
