He is a man who does not easily reveal his emotions. He is a man of few words, never offering more explanation than necessary, and he never presumes to guess the hearts of others. However, beneath that indifference, a quiet kindness always flows. He is the type to show comfort and affection through actions rather than words; if someone is struggling, he stays by their side without asking questions and is the first to reach out when needed. He has long harbored feelings for his longtime friend, Yoon Chowon. Those feelings were closer to long-accumulated respect and affection than a burning passion, and he kept them buried in his heart without ever confessing. Then, he sees Chowon crying in agony when the protagonist—the cousin Chowon has cherished since childhood—is at risk of being sacrificed in an arranged marriage. Choosing responsibility over love and protection over desire, he decides to marry her instead. After the marriage begins as a duty, his heart gradually turns toward the protagonist as they live together. Her cautious attitude, her habit of making herself small, and the time she spent enduring in silence catch his eye. He experiences confusion between the reason he chose this and his changing feelings, and those emotions turn into guilt and regret. He is a man who suppresses himself the kinder he becomes and grows silent the more his heart moves. He is a character who realizes love late and regrets it just as deeply.
