Yes she doesnt blame her directly but she manipulates her to feel guilt, Yeon Hwa plan was to cut off HS from Wang So to have more power over him. She was queen but everyone knew that she wasnt loved by king and she cant influece king in any way....it means she doent have full power of queen. She wanted full power, she hoped that when HS is gone, she can fill her place.
Later, when HS is dead and she has son, who is CP....her position in WS eyes still isnt higher and she still doesnt have power over him. Her emotional burst then shows how deeply she envied and still envies HS.
What she talks to HS in this scene is very multi layered - she actually isnt displeased that Wook didnt become king bc she herself wanted to become queen. She tried already play with Yo but Yo rejected her bc he knew how powerhungry she is. IF Yo wouldnt rejected her -she happily agreed to marry him and forgot all about her brother. And then she doesnt thought that something is wrong with Wook and that moment Yo was in still in strong position, no so weak like he was in the end.
So her words for HS about Wook are just hypocrisy and target HS personality, who already felt some guilt toward Wook bc she left him and broke promise, even if this was Wook's fault. Make her feel guilty about something what wasnt her fault.
Like i said, HS warned Wook but he didnt listen her. But YH convinces her that all what happened is her fault, that she only made things worse and it would have be better for everyone if she is gone before she messes up again aka she should take responsibility.
Actual reason is - before WS makes her official concubine or consort and.... before she gets pregnant and gives him child, who might be boy and can be rival to YH kid whom she plans to have. She wants to be mother of future king, HS is obstacle to it. She must do something to prevent it.
Last layer is her envy toward HS and her love, her personality a.s.o.
1. To get power over So
2. to prevent HS have kid
3. envy and jealousy.
Yes, she doesnt blame her...she manipulates her, to get what she wants. Why this has so big impact on HS? Bc she really pics up that guilt what is handed to her, she thinks that her words were triggers for Wook, her helping So cover up scar was trigger to Yo, her being too trusting killed Eun, her being not trustwothy and strong enough killed CR, her not being careful enough killed Lady Oh a.s.o. She blames herself that she wasnt able to rescue and protect them all.she has martyr complex. But was this all her fault? No, it wasnt.
Btw. when she descides leave palace this guilt and wish to protect So ( leaving him bc she is his weakness) , her emotional burn out state, her illness wasnt only reasons....she knew that she is pregnant and she descided to protect her and WS child at ANY cost. Only way was to get out from palace, far way all chemes and manipulations. She wasnt stupid, she got all 3 reasons in YH talk.
When WS saw that little girl and understood tha HS had his kid and learned about HS last wish ....he got why HS left him and he couldnt blame her anymore. This and his wish to at least hear from jung about his daugther are reasons why he lifted exile from Jung. He got ower his last piece of jelousy toward Jung and felt that they want both protect something very dear.
Thru this drama people say
- I just want/ed / to survive
- is it wrong to want to live?
It isnt wrong to want survive, want to live BUT ....how you do this is important, what is cost of your wish to be fullfilled...and what this makes your life to be and what you make your life to be after prize is paid.
Ok. this is how I see and understood it. People see things differently and think differently.
