Orc-ishly Ever After

My fiancé's mother is a real monster-in-law & she's determined to break us up.
I've been dating an orc, Jarum, for a few months when he proposes. I hesitate before saying yes. I want to be with him, but I'm nervous about what might be expected from an orc bride. When I agree, he says we can't fully mate until his parents approve and I've completed two ancient orc marriage tests.
We love each other, so the tests will be easy, right?
We travel to the orc kingdom, where I meet his mother, who implies she doesn't think I'm good enough for her darling son. Then she begins the tests. Who would've thought impaling her in the chest with an axe would impress her?
As soon as I please Jarum's mom, he and I will be joined in wedded bliss. But one cultural blunder on my part leads to another, and I worry I can't make this work.

Can a human and an orc merge two worlds together to find their happy ever after?
