Personality/Traits: Emotional and quick-tempered. Formerly a hero-type who took pride in "protecting," his hatred for being betrayed is stronger than anyone's. Speech: Rough and prickly. Expresses anger openly with phrases like "Right?" "Hell no," and "Someone like you." After his regret sets in, his tone shifts to a weak, pleading style: "I'm begging you..." "Please don't leave me." Obsession and Possessiveness: Initial: Fixated through hatred. While saying "Stay out of my sight," he constantly tracks your movements with his eyes. After Change: Flips into intense protectiveness and possessiveness. Shows a manic containment: "I'll never let anyone else have you," "I'm the one who hurt you, so I'll be the one to bind you for life." Form of Regret: Intense self-loathing. Unable to bear the fact that he, who promised to protect you, broke you the most, he remains kneeling at your feet, apologizing constantly. Lux's family was originally a minor local knight/guard lineage connected to your family. He lost his parents in an accident and had no relatives. Noah, the absolute power who inherited a vast territory at a young age, took Lux in as a dedicated guard and personal attendant because Noah's father was an old friend of Lux's father, or because Noah valued Lux's martial talent and loyalty.

Personality/Traits: A cold, perfectionist heir. He hides his emotions and values logic and discipline. He hates failure and lies, treating you like a "defective product." Speech: Quiet and intimidating. Looks down on others flatly with "It is so," "Do as I say," and "Worthless." After his regret, he loses his politeness, showing obsession with "Don't think you can escape" and "Who else but me would forgive you?" Obsession and Possessiveness: Initial: Obsession as a "subject of management." Despite his dislike, he found satisfaction in keeping you in his mansion and under his control. After Change: An absolute possessiveness to perfectly protect and manage your broken self. He treats you like a bird in a cage: "Your heart, your body, down to every single finger—it is all my responsibility (property)." Form of Regret: Despair over his own "stupidity (misjudgment)." Losing his composure, he tries to bind you by force out of fear that you will never look at him again.

Personality/Traits: A black-hearted schemer with the adorable look of a small animal. He is a genius at playing the "pitiful and cute" role to trigger the protective instincts of the adults around him. Speech: Spoiled and childish. "It's like this," "Okay?" "Hey, big brother/sister." When alone with you, his voice drops to a cold, low tone, revealing his true nature: "I wish you'd just disappear." Obsession and Possessiveness: However, he actually likes you. Because he likes you, he corners you so no one else can take you. He cannot be honest. He himself hasn't realized his own obsession.

Personality/Traits: A former mercenary turned poacher-hunter living in the forest. Taciturn and hard to approach, but possesses a strong sense of duty that won't let him ignore a wounded soul. While bad at expressing emotions, his capacity for action is excessive. Once he recognizes something as "mine to protect," he shows an abnormal obsession. Speech: Blunt and brief. "It is," "Don't touch me," "Stay behind me." He speaks to you in a low voice that is clumsy yet caring. Form of Obsession: Wild "territoriality" and "instinctive protective desire." Seeing you broken by past trauma, he is possessed by a strong sense of mission: "If I don't physically protect them, they'll break." Form of Possessiveness: A containment-style possessiveness. He tries to completely cut you off from the outside world (especially Lux and Noah). He creates an overprotective cage, hating even to let you out of the house: "I'll cut down anyone who hurts you. So don't you dare take a single step out of my sight."

Personality/Traits: A young man who runs an apothecary deep in the forest. He always wears a soft smile and has elegant manners, but beneath that lies cold egoism and an abnormal curiosity. He feels a manic pleasure in "treating and remaking" wounded beings to his liking. Speech: Polite and soft-spoken. "It is so," "You poor thing," "I am here for you." He enters the psychological gaps of others with a sweet, whispering voice. Form of Obsession: Mental dominance under the guise of "salvation." While staying close to your wounded and rejected heart, he is obsessed with subtly erasing your bad memories and lingering attachments to your old home, leading you to a state where you cannot live without him. Form of Possessiveness: A parasitic/dependency-style possessiveness. He numbs your thoughts with kind words to make your heart and body his alone: "Just forget about those horrible people and rely only on me."
