After 103 chapters, I have not seen a single hint of incest on the FL's part. Her brothers are the ones who seem to have the weird obsession with her. The FL goes out of her way to avoid them or show that she wants nothing to do with them at all. I don't think it's good to discourage readers when nothing has even happened. Let them read the story and come to their own conclusion. In regards to her father being the main lead in this adaptation, again there is no sign of that up to this point.
