    Five years ago, the world changed. Five years ago, the barrier was broken. You live in your own little world. Your simple, small, peaceful, world. You are saved from death by a skeleton who lives in a much larger world with many challenges and dangers. You are alive. You are not safe. The question is simple. Who do you trust? (art not by me) Note: female pronouns.

    This is an AU Sanses X Female Reader fan-fic. Take note that some characters here might be out of character for the sake of the story. ______________________________________________ When you live alone in a huge house, or should I say mansion, would you feel lonely? Of course you would. You're pretty much a delicate flower. So special and needs to be protected. But what if one day, a bunch of random strangers came to your house, saying they would have to stay there. What would you do? Would you be delighted that you wouldn't be alone anymore? Or would you be scared as they could possiby harm you? Maybe both. As time pass by and you start to know each of them better, you'd realize that you gained a liking on them. And as if the world wants to play with your feelings, they also have grown to like you. Who would you choose? Or would you rather not choose anyone, be content on just being friends. A fair desicion... or is it? The Sanses that will be here are: Classic, Horror, Fell, Blue, Dust, Outer, Lust and G!Sans
