This is an Undertale fan fiction about a girl who falls into the underground and falls in love with Alphys

After discovering her dark secrets, you distanced yourself from Alphys for a while. Everything had happened so fast, you just didn't know what to do. But, one day, she called you and invited you over to watch some anime with her and Undyne. Nothing special. Until Undyne has to cancel, leaving just the two of you. You start to discover another side of Alphys, realizing that, even after all you had been through, you did not know her as well as you thought you did.

You have had a crush on Alphys since you've met her and it your chance to tell her because her and undyne broke up.

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister. Please note the the story is primarily on Quotev, so updates to Wattpad may be late, or lag behind that of Quotev. The story also has the potential to become mature. (I haven't decided yet.)

You've heard the stories, of the mysteries of a man who guides lost ladies home by night legend says his voice is like a demon of hell and anyone who's ever approached him has died. One night you get lost and you uncover his real story

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!

Everyone is finally above ground, Sans is on his own journey into the world and He suddenly meets the girl of his dreams. Will his love be accepted? or will humans and monsters never be able to be together

This is a female reader x fell sans. (Y/N) was a kind girl. She loved her family and her friends. One day something went wrong and she fell into the Underground from the top of Mt.Ebott.

Will (Y/N) and Sans finally realize that they have feelings for eachother, or will Asgore find (Y/N) before it's too late?

After explaining Christmas to the monsters with Frisk, you all decide to get presents for one another. Everyone was easy, but....not your crush....Undyne.
