MC had 3 kids with MLs, 2 twin sons and a daughter. And her brothers were very possessive of her and it's implied that they wanted to keep her at home forever (even MLs intented to do so). And the daughter, like MC, also wasn't impressed by other man's face because they weren't as good as her brothers.
But the problem was, while MC wasn't the real sister of MLs, her daughter was the biological sister of her sons. Well, with the power of the dukedom, maybe they didn't care much about morality?
Evan knows that FL is not their sister,not biological sister. FL fucked both men,she said she loves them both equally. The villain is the crown prince,he will discover their secret and used it as a threat. The crown princess is not treated well by her husband the cp,and she's a Marquis's daughter. FL should be cp's wife but the duke refused to marry her to other man,so he gave up an island just to keep FL. The duke will negotiate with the second prince to become the cp, they'll planning against the crown prince. No one opposed since cp is not a good person and crown prince to his people. In the end,FL married Evan,the big bro but keep Leon as her lover. The three of them lived together and produced a daughter. So,the daughter became like her mother who loves her brothers. Like mother like daughter... FL is a daughter of a gigolo or courtesan (?) and it will be known since their secret was leaked. Evan made a negotiation with second prince's mother(?),I think there's an adoption, something like that. So Evan married FL and Leon as fl's lover.
