He doesn't have a sister, it was just a pretend one. His parents don't live in the capital, he used that as a reason to make it look like they had a daughter while they were away.

They had a daughter but the mother wasn’t there? I haven’t started reading this cause i always see bad things about this manhwa in whatever way

What? Cesar in an only child of the Duke and the Duchess. Cesar didn't have a bioligical sister that looks like Adelle, both his parents left him when he was a child. Adelle somehow resembles Cesar, with her hair color and eyes that's why she's the perfect fit for the role of a long lost sister that actually didn't exist since his parents left him they used that as a reason that they had child when they were away. Adelle wanted to get out of her messy life so she made a deal with the Duke since Cesar didn't have the intention of getting married at first, so in order to repay the help Adelle received she's the one who's getting married instead of him. I'll stop here. And I suggest you keep on reading so you'll understand everything.

Oh okay so the parents told her to act as the sister i thought it was cesare

Um I think you should just read the whole story, it was Cesar who told her not the parents she only just met his parents in the recent chapters

Idk though cause I deeply hate playboys and from what I saw by the photos of this manhwa he was a huge manwhore

Like at the moment I have no will of getting irritated by a ml’s being always with other women

Oh and also the fumbasses things he says like the confession during carnival
