Y/n fell into the underground when she was 13. When she 1st fell Chara tried to convince her to be her "friend¨ but Y/n, being smart, disagrees. Chara becomes angrier as Y/n keeps sparing everyone. Chara knows Y/n isn strong enough to leave the unground by herself yet,so she has 5 years to get into Y/n's mind, to break Y/n. Sans knows what Charaś been up to. He has to stop her from getting to her. To Y/n. To HIS Y/n. To his Snowflake.

Your the daughter of Cross Sans. This story goes on to from Baby years, to Toddlers, to middle age, to teen, to adult years. Cross calls you his little X (the X will be in bold). Hope you like and keep on reading. Also there maybe a X-Event! Also when Papyrus is talking he ain't yelling... thats just how he talks.

An unexpected turn of events lands you in the depths of Mt. Ebott. Upon waking up, you found yourself with a interesting and skeletal duo. {Completed} Thank you so much for 10k+ reads and 300+ votes! \o/

Won't let me update chapters anymore, so move to my other request book if you have any requests see you there ^u^

This is the second story to "Unexpected Love" so if you haven't read the first book you should probably read that first so you aren't confused. But anyways, enjoy! You wake up on the cold floor in the old lab that Alphys had found. You felt strange and the only life form that you could find in the Underground was Chara, who had somehow gotten out of your consciousness and now looked like a normal human. You find out that six months had passed and a child named Frisk had freed everyone and the barrier was broken. Now, with Chara somehow befriended, you leave the Underground in search for your monster friends. And most importantly... Sans. Author's Note: enjoy my awful writing! ((COVER ART IS NOT MINE))

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))
