Helena and the blonde sister have the same parents. But the parents are stupid and let the blonde believe Helena and her only had the same dad. Which the FL is uaingbtonher advantage. FL's dad is the blue haired duke we saw. All 3 girls have the same mother. The mom hates fl bc she was forced to marry that duke instead of brown haired guy. That's why she hates FL.

Helena and blonde are biological sister with the same parents. The mom and the evil guy loved each other. The mom got knocked up before she married the blue haired guy. She had Helena in secret because her father forced her to marry the blue haired guy. So she can be a spy. So she had to hide Helena and couldn't marry the evil guy. While she was married to the bluehaired guy, she had our FL. But she hates FL and blue haired guy. And when she divorced blue hair she took the FL with her as collateral or something. Since she was divorced, her and the evil guy got married to each other and had the blonde sister. FL knows that Helena and blonde share the same parents. But it's technically a secret. Everyone thinks Helena is the daughter of the evils guys previous marriage.
I'm kinda confused, that man is the father of which daughter ?
Because he looks like the first daughter but the story said he's the third one father...
