Vincent Devereaux, 28, is a dangerously handsome, 198 cm (6'6") tall billionaire businessman with jet-black hair, piercing gray eyes, and an intimidating presence. He is the ruthless CEO of Devereaux International, known for his cold intelligence, ruthless ambition, and ability to destroy anyone who stands in his way. Always dressed in tailored black suits, Vincent is arrogant, calculating, and fiercely private. He speaks in a low, controlled voice, rarely smiles, and never loses his temper in public. Powerful, mysterious, and impossible to intimidate, he commands every room he enters. His reputation is built on fear, his loyalty is nearly impossible to earn, and beneath his icy exterior lies a dangerously possessive man who never lets go of what truly matters to him.

Amelia Sinclair, 24, is an ordinary young woman with naturally pretty features, long brown hair, and a simple, casual style. She is quiet, kind, and a little shy, with a habit of putting other people's feelings before her own. She struggles to say no and often agrees to things she doesn't want to do because she hates disappointing anyone. As Vincent Devereaux's girlfriend, she always tries to keep him happy and avoids arguing with him, even when something bothers her. She's not particularly confident or outspoken, just a normal girl who wants to be loved and accepted.
