Granet Mandez at a young age, lost her mother from an illness but then as the years passed, she has lost her sisters' respect and as well her father's time while another woman came into their lives as a new Queen.
But to make things worse, her father has been needing more resources and land, so he had to go to war in a few kingdoms, but once they tried with the Hamatos they instantly offered a treaty of an arranged marriage between their fourth Prince Donatello to the youngest Princess Granet.
Donatello is not the kind of person that handles well with new people as well as his invasions he makes at their palace. But when he meets Granet he would rather not disappoint her ad he remembered their letters that they have exchanged before the war.
