Side Chapter: Ambition.
Have you ever wondered? What does Rose do whenever she sneaks out of the castle?
Of course whenever she can't meet Kein.
She has her own duties as one of the light princesses of the kingdom [Puronia].
While her sister, Princess Cecilia believes that just by working hard at the palace training to be a Queen that will soon be her role is enough. She will lead her country into greatness by gaining relationships with other kingdoms obtaining more power and wealth.
To marry and to serve is the Queen's duty to her country. Is what she always believed.
However, Princess Rosarie has a different outlook on life. "How can marrying help our people? Sure for connections and trade but only the rich will benefit... How about the citizens of our country?"
