- Crossdressing Voices: Mitsuki Saiga voices Wholesome Crossdresser Kuranosuke making this a case of Recursive Crosscasting.
- Playing Against Type: Junichi Suwabe, who has a long list of Large Ham / Smug Snake characters under his belt, plays the quiet, serious, 30-year-old virgin Shu.
- Schedule Slip: Twice. The series first went on hiatus in December 2014 and returned in July 2015. And just as sources announced that the final chapter was approaching, the series took ANOTHER hiatus from January 2016 to June 2017 as the author was focusing on her other work, "Tokyo Tarareba Musume" which ended in April 2017.
- Write Who You Know: Tsukimi is almost exactly how the author was as a young girl, jellyfish obsession and all, but aged up for extra pathos.
