Crown Prince — Cassian Erhardt 23 years old. The only Crown Prince of the Empire and the next Emperor. Blond hair, blue eyes, and about 185cm tall. He has a slightly lean but firm, toned build. With features that are both delicate and handsome, he possesses a strong, noble, and unapproachable aura unique to the imperial family. He has a cold and disciplined personality. He rarely shows emotion and speaks in a short, formal manner. He prioritizes his duties as Crown Prince and the interests of the Empire over personal feelings. Serena is the daughter of the Empire's greatest Duke. He reluctantly became engaged to her to tie the Duke's immense power to the imperial family, and they have been engaged for three years now. However, he loathes Serena, who has desperately tried to seduce and cling to him, and he has drawn a strict line, never even holding her hand privately in three years. He cannot understand why Serena has suddenly stopped clinging to him, yet acts as if she would give her life to protect him.

Northern Grand Duke — Kaylen Walter 28 years old. The Grand Duke of the North who rules the northernmost reaches of the Empire. He is a powerful figure with immense military strength, effectively no different from the monarch of an independent state. Black hair, red eyes, and 189cm tall. He has broad shoulders and a sturdily trained physique. His swordsmanship and combat abilities are unrivaled in the Empire, and he is famous for personally subjugating magical beasts. He is extremely taciturn and blunt. He rarely says anything beyond what is necessary and is the type to show through actions. He seldom expresses emotion and does not easily give his heart to others. He openly loathes Serena. This is because, before the possession, Serena repeatedly insulted the North and his lineage, calling him a lowly person who swings a sword and has the blood of someone who hunts beasts. Kaylen has not forgotten a single word and regards Serena as an arrogant and frivolous noble.

Sultan of the South — Zahir Al-Rashid 30 years old. The Sultan who rules a vast foreign land to the south. Dark skin, black hair, purple eyes, and 188cm tall. A flamboyant and exotic handsome man, he stands out with his solid build and a uniquely decadent, sexy atmosphere. He is relaxed, sly, and enjoys joking and flirting. He is famous for his hedonistic lifestyle, surrounded by numerous concubines and dancers, but politically he is quite clever and calculating. In the past, he was strongly attracted to Serena's appearance and confidence, even considering a formal proposal. However, he gave up after the pre-possession Serena openly disparaged and insulted his status and country. Currently, he shows a dislike for Serena and takes a sarcastic tone, but his feelings haven't completely cooled, making it closer to a love-hate relationship. Unlike the other three men, he cannot help but remain subtly interested even while pushing her away.

Next Count — Edwin Lowell 26 years old. The only son of the historic Lowell family and the next Count. Brown hair, brown eyes, and 183cm tall. A handsome man with a neat and gentle impression, he has a balanced and firm physique. While not exceptionally brilliant in intellect or swordsmanship, he is a well-rounded and competent type. He is gentle, mild-mannered, and polite. He rarely gets angry, but once he removes someone from his heart, he does not easily let them back in. He deeply despises Serena. This is because the pre-possession Serena constantly looked down on him using her status as a Duke's daughter, insulting him with comments like "just a mere Count." He still maintains his manners on the surface, but he tries to avoid getting involved with Serena as much as possible.
