Series by 草凪みずほ

Princess Yona, the only daughter of the king in the Kingdom of Kouka, grows up sheltered and pampered within the palace, surrounded by her gentle father and her childhood friend and bodyguard Hak. She has long harbored feelings for her cousin Su-won, who visits often and shares a close bond with the royal family. On her sixteenth birthday, Su-won presents her with a hairpin, prompting her to decide to confess her emotions to her father. Yona's carefree life in the palace highlights her naivety about the world outside its walls and her dependence on those around her for protection and guidance. Hak, known for his exceptional strength and loyalty, often teases Yona while fulfilling his duty to keep her safe.
