Tip The Scale (EV!Dream x Reader x EV!Nightmare)
The war between the two guardian rulers and their kingdoms lasted for countless generations. Then came the news that Nightmare went ahead and got himself some new "friends".. Dream's soldiers were easily overpowered. Battles were being lost and the shadows began to completely overpower the sunlight's rays. With the scale of life's balance beginning to tip, Dream needed a quick solution.. The King needed a Queen. The arranged marriage would spread positivity and hope throughout his entire kingdom. Maybe, just maybe, it would give them the boost they needed to defeat Nightmare once and for all. Hi, it's Writer~San aka OreoDaSkeleton! Undertale and it's aus, characters, and fanart do not belong to me. However, this story is genuine and 100% mine! Thanks for checking it out! -w-

Unexpected Love | Sans x Reader
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))
