I Traded Three Beasts for One Wolf King — Episode 16

Eldest princess Elsa keeps three fox beastmen—until they see her sister Luna. She trades all three for Luna's untouchable cold-faced werewolf. She wanted a servant; yet he bows only to her, and once he bites, won't let go. Forced to marry, she signs, schemes, and flees on her wedding day. Then the foxes kneel begging her back—but can't pass the gates. When the capital falls to chaos as Luna drains the treasury, Elsa returns with the mountain king. What she wants back was never just the throne.
