Katsuki worked as an entertainer for the Royal Family. He was a violinist.

. Katsuki didn't really enjoy his job, but he needed the money... And at least he got to see you every day.

. You were the princess. Forced to be confined within the walls of the grand, over the top, prissy, palace. It got boring real fast.

. One day you were walking through one of the many hallways, searching for something to do. The walls were white marble, lined with expensive artifacts, and framed pictures of you and your family.

. You heard music playing in the entertainment room. Where your parents often went to entertain guests.

. So you went in, cautiously looking around. You saw Katsuki there, practicing. Your parents were going to have guests over later.

. You walked up to the stage, where he was. He saw you and raised an eyebrow. But went on playing. You smiled at him and stood in the middle of the stage.

. He played and you started dancing. You two were practically in harmony.

. You didn't know it, but your parents guests had arrived early. Your father, the king, your mother, the queen, and their friends, who were from a neighboring kingdom, heard the violin music and got curious.

. So they peeked inside and were surprised to see you dancing gracefully, doing leaps, spins, all kinds of different things, like you were a professional ballerina, while Katsuki played his heart out behind you.

. The two of you were in a bubble no one could burst. In your own world. Absorbed with one another, and the music.
