Putting Lilliwyt a slightly different way: that's all swept under the rug/doesn't matter/don't ask.
I wouldn't really go quite that far. Fact is, while kokoa does have a point to some extent, most of the criticism would be valid for the parent series, but not really for Citrus +, either being related to events that happened before the time span covered here, or to questions left open at the end of Citrus, meaning that this series has either not reached the point where they even become an issue yet, or they might not even be in the scope of this series to solve unless it is eventually extended beyond the end of Citrus itself. Also, with this still being an ongoing series, we can't be absolutely sure some of these points won't be still addressed in future chapters (as unlikely as it may be).
