Another things is we're still waiting for a real ending to Tachibana-san. Not the "yeah, the guys got caught, but the girls may need to go "take care" of something they got from the guys at a doctors office, and the boy may see the tape of the girls night that has some samples floating around despite the mother's cop/detective friends best effort" one page epilogue we got.

Even more so is(if i recall right; i just kind f skimmed) this is actual incest and an actual kid, making it all kinds of creepy.
