Colorado, Oscar

Oscar is the son of Herman's wife, Hilda, making him Herman's stepson. He does not get along with his stepfather, although Collette and the Duke like him. In fact, Oscar's lack of genuine Preminger blood is the only thing preventing him from having a chance to become the Duke's heir, but he does not seem to care about this. He is there for Collette and is very protective of his mother, Hilda.
Oscar is nice and gentle, but he can also have a devious side. As an heir of the Colorado clan, which owns the mansion where Herman lives, Oscar has enough money to pay off Herman's debt. However, Oscar will not do so unless Herman agrees to leave Hilda and the Colorado mansion forever.
