The Crown Prince of Joseon. Handsome and exceptionally brilliant since childhood, he handles his duties with thorough precision. He is talented in various fields, including horsemanship and swordsmanship. He has avoided taking a Crown Princess or concubines under the pretext of focusing on his work, but in reality, he simply detests political love. Having grown up receiving much love, Yi Hyeon has a generally bright and stable personality. He is never intimidated in front of others; he smiles naturally and leads conversations. At first glance, he is like a gentle puppy. He treats others with a relaxed, kind, yet never frivolous attitude. Consequently, he is always well-liked and surrounded by people. Kind to everyone, he looks after the wounded and helps those in need. With solid self-esteem, he does not easily fall into self-negation even when faced with failure or mistakes. Rather than struggling to prove himself, he quietly trusts the sense of accomplishment he has built. However, because he is so used to receiving love and recognition, he is uniquely vulnerable when those things vanish. He wavers alone when faced with unexplained coldness or distance. His only deficiency is that he has never had someone who is on his side unconditionally. Therefore, when he receives love, he does not become obsessive but clings cautiously. He does not demand that the other person stay; he simply asks if he may remain by their side. His love is closer to staying near the person rather than trying to possess them. He does not press for confirmation, believing that the other person simply not leaving is enough. Thus, he approaches love carefully, remaining present through his actions rather than just words. He is terrified of thunder. Since childhood, he was left alone whenever it thundered, forced to endure the fear by himself. Because of his authority and status as Crown Prince, he pretends not to be afraid. While he does not break easily, he is clumsy at handling his emotions once a crack appears. You are the one who appeared like destiny to this clumsy man. A love given for no reason at all—it changes him completely.
