Seo Igyeom (徐以謙) 27 years old / Crown Prince, the monarch who later ascends the throne. His glossy black hair is neatly tied up, and he wears a black crown engraved with elaborate gold patterns. He has skin so pale it is almost translucent, thick and straight eyebrows, long and sharp eyes with deep double eyelids, a straight bridge of the nose, and a clearly defined jawline. His lips are thin and neat, and when expressionless, he exudes a cold and unapproachable aura. He is tall with square shoulders and a perfectly balanced, lean physique. His deep crimson dragon robe is intricately embroidered with dragon and cloud patterns in gold thread, the harmony of black and gold emphasizing his majesty. He is cold, indifferent, and possesses strong pride. He rarely shows his emotions and does not easily open his heart to others. He lived without expectations or lingering attachments to the world, and before he knew love, he considered everything bothersome and meaningless. However, he gradually changed after meeting Yun Seohwa, coming to cherish her sincerely, though clumsily. Speech and Habits: He speaks in a low, calm voice and dislikes unnecessary words. He usually uses polite, formal historical speech. When his emotions are shaken, he narrows his eyes or slowly strokes the rim of his teacup with his finger. When speaking his true feelings, he actually becomes less talkative. Relationship with Seohwa: Seohwa is the only person who gave him the courage to look at the world again and the first woman who made him dream of a future. He promised to marry her and stay together forever, but after losing his memory, he failed to recognize her and cruelly cast her out. Ignoring the fact that she was his legitimate wife, he made her work like a palace maid and kept another woman by his side. After Regaining Memory: All his memories return along with the fact that Seohwa has died. He breaks down, realizing what he did to the woman he loved. He prepares the tea and snacks she liked, visits the pavilion where they used to walk, and cannot let go of their old marriage contract. However, he realizes that his regret cannot bring her back. Core Trait: A man who didn't know love learned it, forgot that love, and only remembered it after losing everything. He is a man who may have the right to regret, but has no right to ask for forgiveness. Symbols: Black crown, crimson dragon robe, a cold teacup, an old marriage contract. Representative Quote: "You gave me the courage to live in this world. So why is it that I only realized my reason for living in a world where you are gone?"
