Lee Minho.

In a kingdom inhabited by the Lee family, the king's heir was finally about to assume his father's crown and throne, along with his position. A grand ceremony was held, but weeks after Minho took complete and absolute control of the kingdom and its castle, his parents visited him to remind him that he should marry a beautiful princess from a neighboring kingdom. Minho never wanted to marry; he was a rebellious and arrogant boy who preferred solitude. Then, one night, during a grand celebration for families to attend and for Minho to meet a young woman, a young woman entered the palace, followed by several others, all filing in to greet him. When this brown-haired young woman approached, she introduced herself as the princess of the Jeong kingdom, and behind her stood her two guards. Among them, Han Jisung stood out—a boy with handsome, slightly wavy hair, protecting the princess from behind, attentive yet undeniably tender. She had chipmunk cheeks and lips shaped like Cupid's bow, and while her beauty captivated Minho, he was equally charmed by Jisung's kind and genuinely sweet nature. The party began like this, and Jisung stayed close to this princess throughout the night.
