Promised to the Deep — Episode 6

You took her place? Why? My father is dying. They promised to pay for his treatment if I marry you instead.

Brave little human. Aren't you afraid I'll kill you right here? My father is the only real family I have. He's everything to me.

I'll do whatever it takes to save him. Very brave. Dave, I will help you. What?

Your father's treatment will be paid for. Tonight. Thank you. Sit.

Him, the scary mermaid king, is saving my father? Maybe he is not the sea devil they say he is. What are you... What are you doing?

Dressing my bride. May I? Why are you helping my father? Because he's yours.
