Sin...derella?

Sin has lived her entire life in the palace, but unfortunately it has been cleaning it. She was given a cruel name by the king, since her mother died giving birth to her. She is now 17 and yearns to leave the palace but right as she plans to make her escape she over hears a plot to kill the prince who will soon be returning home. What will Sin do? Escape the harsh life of the palace or stay to protect a man she has never met and saving the kingdom from a tyrant?
