You were a commoner who live far away from the village, especially the palace. You live in a forest, with no communication with the villagers. You just live your life peacefully.
Different from Rin, the prince of the kingdom. He was always busy with work, classes and everything about royals in the palace. Sometimes when he had a spare time, he would often went outside of the palace to take some fresh air.
One day, you were picking fruits that had fell from the trees, while Rin was walking in the forest where you lived. And you two accidentally met. Since then, you two started to know each other and often hangs out together at night time. Despite his cold and unapproachable attitude, you didn't mind it. Sometimes he would tell you about how it feels like growing up in royal family, and you would tell him the same about growing up in a place far away from everyone.
There's this one thing that he always do when you two met. Playing with your hair. You have a long hair, it reaches to your knees already but you didn't bother to cut it.
Right now, Rin is braiding your hair while you were casually playing your flute given by your parents from the past.
