It's honestly terrible, as expected. Twenty minutes of sheer nothingness. During the very last minute, though, there's an actually funny (inside) joke referencing another dorama with Moririn, i.e. "Kakegurui". Hence the enhanced grade: 1/10 to the series, 2/10 to the SP. (If they keep them coming, in a few years they might end up showing us something deserving of the passing grade, LOL!) My advice is: watch it only if you're a desperate fan of Morikawa Aoi or Nakamura Risa, otherwise avoid wasting twenty whole minutes of your life on this.
