Warning! There is a chance that there will be spoilers for the pacifist run of undertale. I recommend finishing that before reading this. There won't be any spoilers for the no mercy run, so don't worry about that! Also, don't worry about anything NSFW/lemon if that's not what you're into-there won't be any of that here. You're a human that's fallen down into the underground. You've decided that you'll stay instead of going home after fighting Asgore and sparing him. Now, you had made some great friendships while in the underground-but one of those friends in particular was one you'd like to be a little more than friends with... Aaaa an X reader fic! I haven't done one of these before, but I hope you still like it!

You climbed the famous Mt. Ebott to prove to a group of your friends that humans don't disappear when they go up the mountain. While walking around the peak, you trip over a root in the ground and fall forward, expecting to hit the ground. Instead, you were met with open air. As you fell down the large hole, you let out a shrill scream before hitting the ground and blacking out. When you wake up, you find yourself in the Underground where monsters had been banished to by the humans. You meet several monsters down in the Underground, some becoming friends and some becoming enemies. One particular monster though, has been making your heart flutter and your tongue get tied. Sans the skeleton. A new threat appears when a human that had been thought to be dead comes back and threatens you and the entire Underground. Will you be able to stop them or will you be used as a puppet and watch your friends die? Maybe the only thing that can defeat LOVE is love... Author's Note: this was my very first story so sorry if there's bad grammar or confusing scenes, enjoy my awful writing! ((COVER ART IS NOT MINE))

Flowerfell is an AU (alternate universe) of another AU called Underfell which is an AU from Undertale. If you don't know what Undertale is you will not understand any of this. Like at all. If you don't know what Flowerfell or Underfell is... go do some research.
