I forgot the story of the MC AND ML, but i remember the side characters' one.
It was about the queen and king. The queen hated the king so much but because she is a queen, she had to think of the country rather than herself so she stayed with him. The king loved the queen deep inside. I think the premise was, the MC convinced the queen to kill the king so that shed have her revenge and thru it, her freedom and thats why theyre now sitting in a living room (cuz theres couches xD) with poisoned tea between them. The king knew about this plan but went anyway bc he loved the queen. I think the queen killed herself first (she drank it too) and died infront of the king. The king was so sad and cradled the dead queen (iirc) but he too died (cuz he drank it too while they were having a conversation about this plan to kill him and that how she loathed him) and yeah they both died in that living room, just centimeters apart.

The MC is the noblest noble woman in the universe and shes been trained as empress since young like her other relatives, theyre all blond.

This MC is already a wife to a duke i think, the duke is black haired. And they have a son that looks just like the duke

The story is about the wife finding herself and her freedom from the duke(?) she loves but has to let go because their love is becoming toxic.

I forgot the plot huhuhu but i just remember the duchess is the type to keep it in even when her honor was being tarnished. I think i remember a scene where she had to apologize/kneel to a lesser noble bc the son didnt like that hes going to be married to a girl. And everyone was shocked bc the noblest women could apologize like that to a lesser noble??????

I just remember the duke is the silent type, i remember him as possessive bc he does love the duchess but he had some mission to do i forgot the reason, probably for power or rebelling.

The title.. dancing in the wind?? Blah i cant remember. But its some poetic stuff
