A certain self-obsessed robot decides that he is your new best friend, and you don't particularly feel up to objecting. And your life is good, with your sister returned to you and a new robotic friend who is definitely only a friend and nothing more. That is, until one weekend changes it all, and you no longer know if you want what you thought you did. Maybe he doesn't want that anymore, either. (GenderNeutral! Reader x Mettaton) (I'm terrible at descriptions help me)

COMPLETE These feelings were just a bug. A bug Alphys couldn't figure out. That's all that Mettaton knew, because after all, he was a robot and you were a human. He ran on batteries, and you ran on food. He had variables and you had hormones. The difference between the two of you could not have been larger.

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.

It was just a normal Saturday. (Y/N) was playing Undertale for the millionth time. She was obsessed. (Y/N) had played all of the routes. True Pacifist, No Mercy/Genocide, Neutral. She experimented with killing certain characters doing different things. Then, as (Y/N) started a new game, she felt a falling sensation, as if she just fell out of her chair. She blacked out soon after. When she woke up, she was lying on a bed of golden flowers. She knew this place. (Y/N) was in the game. She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself. I do not own the cover or any of the pictures that will show up in this book• *If you're reading this as a guy please just change the pronouns to he/him/his. I find if a lot easier to just put female pronouns. Thanks! :3 *
