Come to think of it, while I totally appreciate her appreciation for women's independence and self-worth, she did basically just outright say her husband was less important than tea, which is pretty amazing. (Particularly for a shoujo manwha!)
I mean he was (at best) sort of barely-acceptable dregs as husbands go for the first half of his marriage, for all that he's getting better, and she practically worships tea, so it certainly seems 100% accurate to her experience, but just coming out and saying it is another matter XD
...okay, okay, I know that's not actually what she meant. I'm just having a little laugh at the Duke's expense.
