"W- Who are you?" "YOU DON'T HAVE TO DO THIS!!" "Just be safe." "Here, let me help you." "I don't want to hurt you!" "Calm down." "Please Stop." "Listen, it's okay." "Don't worry." "Be careful!" "Everything's alright." "I won't ever let you get hurt." "I Promise." "I Promise." ~~~~~~~~~~~~~~~~~~ "(Y/N)!?"

Your a 18 year old girl named (Y/N), you've been living in the underground for 1 week and you've been staying with Tories. You had run away from a family who never really loved you except your brother. So you tried to do what most people would have done and tried to commit suicide. That plan had failed and that's when you met Toriel. You hear a noise while getting a glass of water, when you go to find Toriel she isn't there. Your panicking and running about the house looking for her. As you turn a corner, you make impact with a tall dark object.

[Y/N] lived with her adoptive mother Toriel for a while. How long is that? About three years. Throughout the time, the monsters in the Ruins know her as if they were her siblings. Flowey became way nicer each day around her, losing his soulless behavior. He cares about her so much he promise to protect her. All was well... Until she sneaked out of the Ruins. Going from Grillby's to the Librar(b)y, she went around having fun. Laws did apply, 16 being the age to leave past curfew, 18 being the age to finally date, and 21 to legally marry. One day, I slipped from my own mouth of the presence of a Princess... And Asgore ordered the Royal Guard to break the door to the Ruins... (Cover art made by Zayn-Inverse on DeviantArt)

So this is a sequel to a story I wrote a while ago. It's called: A whole new experience (Sans x reader). You should probably read that before you dive into this emotional rollercoaster. I mean, it's not like I can stop you. Just saying. If you want to read that story first you can look it up on my profile or type: A whole new experience (Sans x reader) in the search bar. I hope you guys like this story as much as the first one. X

A Sans X Reader story ;P
