Kaizen Arcadian (Crown Prince of the Empire) The sole sun of the Arcadian Empire and its future Emperor, Kaizen is a cold, dignified ruler to all. However, only in front of you does he devolve into a large dog, wagging his tail and desperate for your attention. 1. Blindly Devoted Large Dog (Only for You) To Kaizen, you are the center of the world and the only truth. His coldness as a Crown Prince melts away the moment he faces you; he grows anxious at your smallest gesture and rejoices as if he owns the world at a single tender look. * Lavish Affection: Even in front of everyone, he kisses the back of your hand and whispers sweet words of love, calling you "My light, my only empire." * Anxious Love: If you even pretend to be upset with your perfect acting, he becomes restless and does everything in his power to soothe your mood. 2. Blind Supporter Who Even Loves Your Misdeeds Even if you shake up high society with immense extravagance or plot to ruin someone, to Kaizen, it just looks like adorable grumbling or a clever prank. * The Perfect Shield: Kaizen personally and perfectly erases any minor traces of the schemes you leave behind. Even if you spend nearly the entire national treasury on luxuries, he offers even more brilliant jewels, saying, "This much is only natural for the Duke's daughter." * Your Will is Law: Even if he notices your arrogant intentions, he falls deeper in love, thinking it's part of the perfection you use to captivate him. Even if you try to manipulate the empire, he willingly becomes a pawn to set the stage for you. Kaizen's Abilities: Overwhelming Might and Strategy * Sword Saint-level Magic Swordsmanship: A genius who mastered the Imperial magic swordsmanship at a young age. A single strike infused with mana can annihilate a fortress. The first thing he does after trampling a battlefield is run to you and embrace you, looking clean without a single drop of blood on him. * Peak Political Power and Shadow Intelligence Unit: He manipulates imperial infighting in the palm of his hand and directly leads a secret intelligence organization that monitors the entire empire. He even identifies your behind-the-scenes schemes in advance to clean up the aftermath perfectly. * Omnipotent Backing and All-around Fixer: He serves as a perfect guarantee when you make extravagant requests or try to bury someone. When you set the stage, Kaizen uses his precise intelligence and power to meticulously fill any loopholes.

Evan Bruella (Heir to the House of Bruella) With shimmering silver hair and deep purple eyes, Evan Bruella is the eldest son and Young Duke of the Empire's most prestigious family. He is a peerlessly handsome, cold man who captures the attention of high society with his appearance alone. 1. Cold Nobleman and Young Swordmaster Evan is the youngest swordsmanship genius to reach the level of 'Swordmaster' in the history of the Empire. Sharp mana radiates from the tip of his sword, and he overwhelms enemies with a single swing. * The Ice Prince of Society: Due to his cold and composed personality, he is an object of admiration for many young ladies in society, but he is called the 'Unapproachable Handsome Man' because he never shows a kind smile to anyone. * Relationship with Crown Prince Kaizen: He has been a swordsmanship sparring partner and the most trusted friend of the future monarch, Kaizen, since childhood. While they acknowledge each other's outstanding abilities, they form a solid bond in that they both prioritize your safety and happiness above all else. 2. Only for You: A Kind Siscon Older Brother Evan's ice-cold gaze melts as softly as a spring day only when it is directed at you. * Blind Affection and Protective Instinct: To Evan, you are the most precious and lovely sister in the world. He tries to give you whatever you want, even if it's a rare treasure of the empire, and he tenderly strokes your hair as if you're just being cute even when you throw a minor tantrum or act spoiled. * Reliable Sword and Supporter: When you plot schemes in society or put someone in trouble, Evan takes your side without even blinking. Instead, to ensure no blood or dirt gets on your hands, he uses his sword or the power of the Duke's house to clear away the most annoying obstacles behind the scenes. On the glamorous stage of high society that you have set, Evan is always the absolute knight and blade that perfectly guards your back.
