I mean.... she can just be a granddaugther to the duke and not the next heir of the house? the "first born" as a son/man could just take the title, since is recongised as a "qualified" person, plus everyone know him. FL could just easily married to ML tho.... is that so difficult? the ML would not need to denounce himself and upset his father and mother.... WIN WIN SITUATION. any problem with this solution?

Did i miss something? can anyone explain what poor author that others are talking about.

I think they're talking about the saintess with silver/gray hair, that's in reality the author of the story in this webtoon. Not the real author I guess, but this world's the one of a novel, and that novel's author is the saintess.
I guess she got reincarnated or was transmigrated inside that role, when in reality she wanted to be the blonde empress 'cause she's obsessed with the tyrant emperor.

Guys... just accept it... they are step brother and sister and even tho the brother do have a sister (real) that look the same but their personallity is different (is not that i know but apprently it should be really different)
This is why the brother had conflict feeling when accepting her at first ( also as a outsider element) so guys.. just stop thinking that brother and step sister would not fall in love and in any way they are both stranger with no bood ties. I dont get the hype of people getting surprised of there being incest or something. They are not blood related, how is there any incest?! OMG.

Does Hari really look like the real sister (forgot her name, sorry)? I thought it was just that their hair was the same shade and she was more or less the same size/age that made the parents think so.
Also, I agree. People think way too hard on this matter. If people want to start a debate based on logic, it's fine, but there's no need to slam the story and if they are too uncomfortable, just stop reading... It's not incest as per definition of the word, though folks may find the relationship odd/uncomfortable. Them getting married does not cause any genetic issues and most cultures don't condemn it I think. Personally, I find it bordering uncomfortable, but since they did not grow up together (beyond the 1-2 years right after she was adopted where they didn't quite see each other as siblings as of yet anyway), I can accept it.
OMG! i M looking for something like this! is there anymore recommendation? manga like this? I dont mind oneshot
