BTS Supernatural FF. 

Y/N: When she was 5 years old she got adopted. She has an older brother. Her parents love her a lot, but her step brother always kept distance from her until he moved out. Now they keep in touch more than before and their relationship became better. 

Step brother: He did not like the whole idea of adoption, but after sometime he just couldn’t pretend that he doesn’t care about Y/N. He lives on his own for the last 5 years and I took over family business. In the last few years Y/N and he got a lot closer.

Brother’s friend: He was frequent guest in our house because his family situation was troublesome. He likes to annoy and tease Y/N . For his age he is a bit immature. Y/N parents always commented that they could make a cute couple.

I will update this frequently with new deatails. Other Characters I will describe when they show up in the story.
