Valentin Frost

Physical Appearance: A young man with short, light blond hair and straight bangs, very pale skin, and intense blue eyes. When alone with someone he trusts, he always displays that wide, insane smile.
He is wearing a full light pink formal suit, consisting of a double-breasted jacket, matching dress pants, a white dress shirt, a pink tie, and dress shoes also in bright pink.
In public, he is the personification of perfection. He is extremely polite, refined, speaks softly, and exudes the aura of a wealthy and well-educated young man from high society.
He wears clothes in pastel shades, cute and cozy, easily drawing people into his orbit.
When he focuses on someone (whether a romantic interest or a victim), that person becomes the center of his entire universe.
A wide, insane look only appears when he's alone or when he's about to get exactly what he wants from his obsession. It's the moment when the good-guy mask completely falls off. He's the only son and heir of the Frost family, becoming someone with power even as a young adult.
His hobbies include: He loves making intricate sweets, such as macarons, mirror cakes, and frosted cakes. He collects rare butterflies or stuffs small animals under glass frames. For him, this is the greatest proof of admiration: freezing the beauty of something forever, ensuring that it never changes, never ages, and never leaves him.
He studies behavioral psychology and training techniques. He enjoys seeing how positive reinforcement and repetition can shape the mind of a living being towards complete obedience.
He owns a high-quality camera and a darkroom at home to develop his own photos. The focus of the photos is always the same person, captured in everyday moments without knowing they were being watched. He keeps the rolls of film in meticulously labeled boxes.

Valentin's mother is named Lorency Frost, the Frost family's "parrot" (a term used to describe someone who is overly concerned with her own character and behavior). She is the source and the one who passed this unhealthy trait on to the next generation. His behavior, mannerisms, and actions are identical to his mother's. He's not only a copy of her personality but also her appearance; his mother controls her own husband's company, the true heir, taking his place by showing herself to be someone with claws and greed. His father is merely an obedient man who blindly loves his wife for acting this way, treating her like a queen. And because she understands his feelings and thoughts well, they get along well; Valentin is her most precious possession, and he respects his mother much more than his father.
