Duke's Contract

Lorraine felt that he was really the unluckiest duke in history, well, the unluckiest! Other mages are improving in strength every year, while his mage's strength is declining year by year. Others have awakened their talent, raised their arms, and shined brightly; but his talent has awakened, but he can only hide it, and he is destined not to survive until twenty-five! If you spend more money, you'll call him a playboy. If you don't hold a job, you'll be idle. When you're tired of laughing, you'll be confused. When your sense of justice finally breaks out, you'll end up bullying others... My brother yells at him when he meets him, and his bad friends run away when they see him... Huh, fortunately, he also has an all-purpose "contracted butler" who can go out on the battlefield and into the hall, has a good figure, can hug, rub, bite and kiss, hehe, besides being a little cool and a little cold... Eh? ! What did you say? ! The contract has expired? !
