īecause of his oath to King Il to protect her, he considers himself a tool for her to use and will do anything for her sake. Embarrassed and confused, Yona runs away and Hak is left questioning himself. Taking one, he starts licking off the excess. After the princess's risky mission, Hak tends to Yona's injuries by pouring honey on her hands, which had splinters in them from collecting the medicinal Senjuso plant, and zones out, thinking of what Jae-Ha had said, spilling the honey all over them. Jae-Ha questions his relationship with Yona often, poking fun at him any chance he gets. After they become fugitives, Yona asks him to call her “Princess”, in order to retain who she once was and he accepts her request with no hesitation. He has been in love with her since before the start of the series since childhood but has grown to suppress his desire of doing anything outside their friendship because of her feelings for Soo-Won. He feels extremely protective of Yona, both on a physical and emotional level, and enjoys teasing her.

Hak shares a close friendship with Yona, and they often playfully bicker with each other.
