Summary:
For some reason, the duke's daughter, Letizia, was plotting to break her engagement with the prince. Her plan succeeded and the prince, none the wiser. But shortly after the engagement was terminated... The King collapsed! 
In that moment, she recalled her memories of her past life as a nurse and she fully utilised her knowledge & experience as a nurse, to save the King's life.
