First half was great, the latter half just...plain wrong. The mystery was more entertaining than the answer, and the end just .. just bad. Would have been great as a 5 episode drama or tanpatsu. The drama might be trying to make the viewers commit seppaku at the end. Japan has the worse record of gender inequality among developed nations and dramas like this seem to celebrate it instead of criticize it. Abenomics will be a failure if Japan cannot get rid of sexism on TV even a little bit.
