Byeongyakan? Nampyeonui Gyeyak Anae

I’m Selena, a daughter born to a family well-known for their fertile women. I was all but sold off in a marriage to a sickly duke whose life hung in the balance, all for the sake of producing an heir for his family. They provided me a medicine purported to aid in pregnancy, and the astrologist advised me good days for sleeping together, but... there was no child.

“So, are there any signs of pregnancy?”

“Ah, I-I'm sorry.”

“You’re useless. What luck do you think won you the position of the duke's wife?”

I couldn't say a word.

"No, excuse me. I only have to look at the sky to pluck a star. That's how I attained this position.*"

*Metaphor: Lit. Plucking a star from the sky: something that's difficult to get/achieve)
