~Best friends with the devil in disguise~

You owe your life to Jin- She saved you in a car crash three years ago that nearly killed you. At the time, she barely knew you, but as she did get to know you, she realized there were multiple layers to your life that you have never told her- and now, she's determined to learn the secrets of your past. She has now become your best friend, her facade extremely convincing- however, you were not as dull as you looked. You were a step ahead of her.
