Marone becomes a knight in order to repay her debt to Princess Safinia, who saved her when she was a child. She asks to be her personal guard but she is rejected by the "hidden princess" who has been living in hiding ever since she lose her mother and twin brother at the same time. Even so, she follows the princess around like a loyal dog, and the princess's attitude gradually softens.

Rather, the princess holds my hand, kisses me to stop my tears, and so on... My Lord is too cool for me—?!
