I've seen some people on this site and other saying that if you like the ending in the final chapter, Chapter 14, that you should not read 14.5. This is most likely due to a misunderstanding. For those who have misunderstood Chapter 14 and 14.5, 14.5 does not suggest that Masaomi & Kenji failed to get together. Chapter 14 makes it pretty clear through story and symbolism that Masaomi and Kenji both get together, and have kids together (due to the kids symbolically portrayed playing at the amusement park), 14.5 doesn't say anything more about Masaomi & Kenji, so we can only assume that they got together after all, and that the Balance Policy saved Japan after 20 years or so of operation, as the population crisis is over. It's a great ending.
