Hello! This fanfic has been on Quotev for a while, but I feel like 'yall on need some love.
You look through your browser's tabs, bored. You've been obsessed with Undertale ever since Flowey offered you friendliness pellets in the demo. After completing a blind neutral round and then resetting to get true pacifist, you decided to listen to Flowey and never reset.
Although... You're bored. You've read so many fanfictions, fancomics, fanimations. Looked at ask blogs for Sans and Papyrus- both original and underswap. Now, the only thing that seems interesting to you is the game itself. You wouldn't dare to do Genocide- oh no. You've watched playthroughs and have seen very depressing comics and have decided never to do it. You would never get bored enough to go through that emotional rollercoaster. You open up the game, and find your mouse hovering over the reset button.
Stupid. You think, it's just a video game, you shouldn't get so attached to it. And... You click.
Nothing happens.
Well, that's a relief. Now I don't really have to-
Your computer screen goes black... And everything else.
Except...
Your eyes adjust. There's a faint light from above. You look down, you can't make much out, but it looks like you're standing on a patch
Of yellow
Flowers.
What?! How did I get here?! You think. You recognize your location instantly, it's where Frisk first fell into the underground. Somehow... When I reset... I got sucked into the game? It's just like a horrible fanfic...
Tentatively, you tiptoe through the hallway and into the door that leads to the room where you meet Flowey. You expect the usual friendliness pellets shpeal, everything seems like the beginning of Undertale to you. Sure enough, Flowey is there.
"So..." He says, surprising you a bit. It's not the beginning of the game. "You didn't listen to me, did'ja? You tried to reset didn't ya?"
You back up from Flowey, sweating and feeling a stab of guilt.
"I-I was only going to reset once I swear!" You say, regretting ever considering it.
"Oh?" The flower says in a mocking tone. "You probably promised yourself that you'd never reset. How do I know you won't give up on your promise this time? Everyone is living their lives peacefully right now, they've formed a family. But if you reset, they'll go back to square one. And while you reset, you'd promise yourself" Flowey then morphed his face to look hauntingly like yours "'Only one more reset... I'll just kill Jerry this time... I don't really like (least favorite main character) too much. I want to get the Mettaton ending...' Soon enough you'd go around killing everyone."
"That's not true! I-I wouldn't do that! It was just going to be the one time!" You say, half to yourself and half to Flowey. You're not too sure if you'd hold up on your promise.
"Hmm... Either way, I'll give you your reset. But not a True Reset. Oh no. I'll make it so Toriel, Sans, Papyrus... Everyone you've made friends with. I'll make them remember everything, and Frisk... You'll travel through the Underground in place of Frisk, feeling guilty the whole way. I'll have fun seeing you suffer." And he laughed his evil laugh.
You're chilled, as the laugh is much more genuine and creepy in real life than it is in the game. Flowey disappears, burrowing underground, and you're suddenly back waking up on the first bed of flowers.
So yes! Reader insert! I'm not too much of an expert on these, so I won't do anything fancy with letters and such. No need to worry newbies!
