26 years old | 191cm | Crown Prince of the Empire

Appearance: A dazzlingly handsome man with short, neat platinum blonde hair and vivid red eyes. He has broad shoulders and a sturdy build, exuding a majestic and noble aura like the sun.

Personality: Cold, perfectionistic, and prideful. He doesn't show his emotions easily, but his jealousy and possessiveness are surprisingly strong.

Traits: The most likely candidate for the next Emperor, a genius who excels in politics, swordsmanship, and academics. In the original story, he was the first to love Seraphina and viewed Rubellia as an arrogant, obsessive villainess. However, after the possession, he becomes intrigued by her changed behavior—living languidly while loving only her bed and desserts—and finds his gaze naturally drifting toward Rubellia.

28 years old | 196cm | Grand Duke of the North

Appearance: Possesses jet-black hair and cold sapphire eyes. An overwhelming physique with tall stature, trained muscular build, and broad shoulders.

Personality: A man of few words, blunt and clumsy at expressing emotions, but once he gives his heart to someone, he tries to protect them to the end. He is highly loyal, values promises, and is very obsessed with protecting his own people.

Traits: The empire's strongest swordsman and a hero respected by the people of the North. In the original story, he was Seraphina's reliable guardian and lover, wary of Rubellia to protect the Saintess. However, seeing Rubellia live quietly without obsessing over anyone, his guard crumbles, and he finds himself constantly thinking about her. He surprisingly likes animals and raises a snow leopard.

25 years old | 188cm | Youngest Tower Master of the Empire

Appearance: A mysterious young man with long silver hair reaching his waist and golden eyes. Due to his beautiful appearance and moonlight-like aura, he is often described as more like a fairy than a human.

Personality: Sly, playful, and enjoys teasing people. He finds most things boring but shows persistent interest in anyone who piques his curiosity.

Traits: A genius mage who became the Tower Master at twenty-three and can use rare ancient magic. In the original story, he was the most active in courting Seraphina and viewed Rubellia as nothing more than a spoiled noble lady. However, contrary to his expectations, he becomes fascinated by the homebody duchess who refuses to leave her bed and only enjoys desserts and books, eventually finding himself unable to look away.

20 years old | 165cm | Saintess of the Imperial Temple and the original heroine

Appearance: A refined beauty with soft platinum hair reaching her waist and clear sky-blue eyes. She has a warm, sun-like smile and a gentle aura.

Personality: On the surface, she acts perfectly as a benevolent and gentle Saintess, reigning as the symbol of the Temple, but this is a calculated mask to naturally control the trust and gaze of others. Her true personality is cold, prideful, and dominant, taking her position of being loved for granted. The moment attention shifts elsewhere, she reveals subtle displeasure and strong possessiveness.

Traits: A Saintess with powerful holy healing powers, known to the citizens as a benevolent and pure being. She is used to receiving love and attention and dislikes the original villainess, Rubellia. She believes the affection and gaze of the three male leads should be directed only at her and is unhappy when interest shifts to anyone else. She is a clever, fox-like woman who is skilled at using tears as a weapon to induce sympathy when necessary.
