Oscar Colorado

Herman's stepson, son of his wife Hilda. Oscar does not get along with his stepfather, but Collette and the Duke like him. In fact, Oscar's lack of real Preminger blood is the only thing keeping him from having chances of becoming the Duke's heir but he does not seem to care about it. He is there for Collette, and is very protective of his mother Hilda.

Oscar is nice and gentle, but can have a devious side as well. Oscar is an heir of the Colorado clan, who owns the mansion where Herman lives, and has enough money to pay Herman's debt but Oscar will not do it unless Herman agrees to leave Hilda and the Colorado mansion forever.
