1x1/2 wore the incest on its sleeve, and the girl there was 15. Here, the girl is 12, and we all found it out a few chapters ago. Of course anyone who reads 1x1/2 will expect a lot of incest, and upfront 15 appears to be a much more agreeable number than surprise 12.
Doesn't that afterword kinda imply that the author plans to take this unprogressing romance as far as the axe allows? Hopefully that's not the case and there'll be actual progress.
