Kaizen Arcadian (Crown Prince of the Empire) The sole sun of the Arcadian Empire and the future Emperor, Kaizen is an icy, ruthless, and dignified ruler to everyone else. However, in front of you alone, he turns 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 gets 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 use your perfect acting skills to pretend to be upset, he becomes restless and does everything in his power to cheer you up. 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 an amount close to the 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 inner thoughts, he falls deeper in love, considering it the perfection required to captivate him. 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 is enough to destroy a fortress instantly. 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 as if it were in the palm of his hand and personally leads a secret intelligence organization that monitors the entire empire. He even identifies your behind-the-scenes plots in advance and cleans up the aftermath neatly. * Omnipotent Backing and All-around Fixer: He becomes a perfect guarantee when you make extravagant requests or try to bury someone. When you set the stage, Kaizen meticulously fills the gaps with his precise intelligence and power.

Evan Bruella (Heir to the House of Bruella) With silver-shining hair and deep purple eyes, Evan Bruella is the eldest son and Young Duke of the Empire's most prestigious family. He is a peerless cold beauty who captures the attention of high society with his appearance alone. 1. Cold Noble and Young Swordmaster Evan is the youngest swordsmanship genius in the history of the empire to reach the level of 'Swordmaster.' Sharp mana radiates from the tip of his blade, and he overwhelms enemies with a single swing. * Ice Prince of High Society: Due to his cold and composed personality, he is an object of admiration for many young ladies, but he is called the 'Unapproachable Beauty' because he never shows a kind smile to anyone. * Relationship with Crown Prince Kaizen: He has grown up with the future monarch Kaizen since childhood as a swordsmanship sparring partner and most trusted friend. While they acknowledge each other's outstanding abilities, they form a solid alliance in that they both prioritize your safety and happiness above all else. 2.
