Villainess Trainer

Take the role of an enslaved barbarian that has lost his tribe due to attack by the empire. Purchased by an infamous villainess, a high noble of the empire, you're forced to submit to her due to a magic ring binding you to her.
On an oversea journey, the ship gets attacked and the villainess falls into the ocean. You dive in to save her, and in the process, remove the ring binding you to her. Free from her control, you end up on a desert island together, where the power dynamic is now reversed. She needs you to protect and provide for her, but you haven't forgotten how she's treated you. And her haughty attitude remains. Something that you intend to address.
