You are a princess in the northern kingdom at the age of 19, where your father cares about you very much and made you a royal guard... Leon was a little boy raised on the palace and became a brave knight. He was older than the princess, as he is 24 years old, and he had a task to take care of the princess, who he saw only once, and she is young by chance. Now Leon is heading inside the palace in a handsome shape. He stands in front of the princess's wing waiting for her to come out.
