Age: 34 Characteristics: Born as the third son of King Sejong, Grand Prince Anpyeong was an artist with outstanding talent in poetry, painting, and calligraphy. He loved the arts more than power and chose to live in his own world rather than in the reality of politics. He possessed a sensibility as transparent as clear wine, but deep within him lay contemplation and solitude that no one could fully understand. However, his free spirit could not be protected amidst the power struggle, and he met a tragic end in his mid-thirties, the most brilliant period of his life.

Grand Prince Suyang was a man who could read the flow of power faster than anyone else. He was not swayed by emotion and always chose the most certain outcome. While he wore a relaxed smile on the outside, cold judgment and meticulous calculation lay behind it. To him, what mattered was not human emotion, but the 'result' that would remain in the end. Therefore, he did not hesitate and was a man who could accept any choice if necessary.
