The resemblance between fl and lucas is uncanny so I bet fl is the real daughter and that's why the duke couldn't find her because she is already at the dukedom? lolol. Wild guess, maybe the real aisha is also the real daughter but duke pose sent another fake daughter so the the duke will have to behead his own daughter? that's why the duke went crazy and became a villain???
soo, after a while i decided to look for spoilers.
mc is his real daughter. her mom was actually a spy but fell in love with him. she had to go back to her dukedom but she was discarded, leaving only mc behind.
so the mother died?
She’s his real daughter…isnt she? I want her to be happy but that would be pretty cliche and predictable. Lowkey kinda hope she isnt because I genuinely think that’d be sweeter that way..but again, at the end pf the day, I just hope she’s happy :3
