Synopsis:

Cecilia, once a noblewoman, is driven from her homeland after the crown prince publicly annuls their engagement and levels false charges against her. Escaping with her mother to the neighboring kingdom of Theophilus, she conceals her true identity and resolves to endure whatever hardships come her way—even a life of poverty. Just as she begins to adjust to life as a commoner, Albert appears before her: her childhood friend and the crown prince of Theophilus.
