His Majesty Returns — Episode 10

Reginald, a secret emperor, gave up the throne for a normal life with his wife, Rosalind, but she turned cold and cheated. Even their kids turned on him, demanding divorce. Reginald reclaimed his crown, exposed the truth, and cut them off. Rosalind, misled, accused him of being a fake. When he proved his identity and exposed corruption, she begged for forgiveness—but he had already moved on with Princess Isolde.
