By injecting chowon with sperm, this is actually pretty common as a second choice or plan B when the husband/male in the relationship is unable to carry legitimate sperm for the wife/female to conceive so like how some people/girls surrogate for other women that are unable to conceive, others women inject themselves with sperm from a willing mab to conceive when the husband cant.
I hope there's one. There's no redemption what the king is doing. Like how would hyungnim ever develop any feelings for the king? I wanna know if hyungnim ends up happy.
If their is any love built it will Stockholm syndrome and I hope there is redemption or mutiny
