Damn, I like Cale so much:3 (his appearance reminds me of Ivan Braginsky a bit, lol) he wants to see the duke's and the duchess' relationship to improve, that's so cute)
I was so confused why they were calling Chamomile, Chrysanthemum, turns out that is just what they call flowers in the Daisy/Aster family in Asia regardless of them actually being of the genus Chrysanthemum.
if there's a lesson to take from this story it would be that if a wife wants their marital relationship to work well, she would need to show her passion/hobby and make the husband to also enjoy it.
