Honestly I hope this series is able to take this down a path different from 99% of other incest themed stories. It always either ends up being elopement (I know this isn't going to happen. Even if they briefly consider it, they wont go through with it) or they break up due to the pressures of those around them deciding their happiness for them.
I want to see this end with the two of them together, or at least not breaking up due to outside pressure (they're still kids after all, plenty of time to find out it's just not going to work out for other reasons). Any other reason and I'll accept it, but I'd like just one story with the balls to give me a happy ending where they find a place together and even if it's not all sunshine and butterflies regarding their family, are able to live happily together.
