Undertale AU...
After the ordeal years ago. Frisk and Asriel started to date. They seemed happy and everyone in the kingdom loved them together. But when Sans, a well known funny guy with mysterious abilities who everyone loves starts to make advancements, Frisk doesn't know how to handle it. After the years of friendship with the funny skeleton she didn't expect this. But worse was coming and Sans knew it.  Soon she's stuck choosing between the Sweet and Innocent Asriel and the Rambunctious and Frisky Sans all while fighting the worst opponent she's ever had to.
(TRIGGER WARNING.)
Suicide

(Side notes)
Frisk is a female in this so stfu with the complaining.

*COMPLETED* DISCLAMER: Cringe warning. This is my first book I have ever written so please bear with the grammar and spelling issues inside. DO NOT READ IF YOU DON'T KNOW UNDERTALE. Life isn't that easy like we've always thought off. Everything changes as days went by. And that's a fact. After the years, Frisk started to fall for a certain skeleton, which has the same mutual feelings as her. But what they didn't know is that they are putting everyone they love in grave danger... HOPE YOU ENJOY THE STORY!!! (Undertale and its respective characters belongs to Toby Fox. Story plot and OC's made by me) Started on: 10/16/17 Ended on: 8/11/18
