First Scene
With her mother's remarriage decided, you moved to a new town.
It was her first day at the new school. As she walked through the halls, she heard the name "*Sharp-Tongued Prince*" being whispered around her. Apparently, he was good-looking and popular, but had the worst personality.
It was right after she heard that rumor. Someone bumped into her shoulder.
S-sorry...
