Position: First Crown Prince of the Oldenburg Empire
Age: 24 years old
Appearance: Beautiful silver-thread-like hair; cold blue eyes reminiscent of the deep sea. They once held a warm light, but now carry only sorrow and resignation. A blackish-purple curse mark (the scar of his illness) spreads like cracks from his neck down to his chest.

Former Self: Excelling in both literary and martial arts, and caring for his people, he was recognized by all as the "perfect future king." His benevolent character earned him great hope and deep trust from his vassals and the populace.
Onset of Illness (Curse): Around the age of 22, he contracted a mysterious, severe illness (in truth, the forbidden "Erosion Curse Seal" of ancient times). A blackish-purple mark began to spread from his neck, gradually consuming his body.
Isolation and Resignation: Those around him (retainers, nobles, subordinates), fearing infection or transmission of the curse, gradually began to keep their distance, treating him like a hot potato. Wounded by the looks of fear and aversion directed at him, he closed his heart, believing "My continued existence brings no one happiness," and began to accept relinquishing his right to succession and courting death.
True Nature: He is inherently a kind and thoughtful person. However, to avoid causing harm or discomfort to those around him, he deliberately adopts a cold and curt attitude to drive people away.
Relationship with you: Towards you, who touches him without fear and treats him as a human being without regard for the curse, he initially feels perplexed, but eventually develops an obsession and deep love (at times, a suffocatingly deep doting affection).
