Is this gonna be incest?

How would it be incest when Rosemary died? Even if Renaldo was the male lead, Rosemary being dead means that they are completely unrelated, both genetically and legally. Would still be SUPER creepy, but it wouldn't be incest.

But luckily, Marie ends up with Prince Rizel in the end. Still creepy, but in a different way. ╮(￣▽￣)╭

I really hope it isn't TTwTT thats her brother! her baby brotheeeeer TTwTT
