Dear Memories (Taehyung x OC) Mythical AU

Mirae was a sweet, caring and kind girl that many adored. Her parents died at a young age (due to mysterious reasons) and she lived with her aunt. She was a gentle soul but was clever as well.. She was sensitive and polite. Always making a good mood wherever she went, but had been hurt many times because of being too innocent to understand certain things. She began to trust people less, but that didn't change her friendly nature.
Mirae found out about a girl named Soohyun and got accquainted with her. She hadn't met anyone quite like her. It intrigued her interest to find some so independent and free-spirited... They eventually formed a bond stronger than blood-related sisters.
Mirae had certain incidents in her past that if I told you, then you may doubt that she might be human...her friend, Soohyun thought the same.
A year had passed and Soohyun found a possible location to track a mythical being. More, specifically, a Vampire. After a little convicing Mirae, they both set off on their journey...
And thats how our story begins....
