Saiunkoku monogatari

I think this anime signifies perfectly what a reverse harem should look like - it goes to the core of what women would want (excuse the generalization, but it comes from exp) in potential partners: understanding, support and freedom to choose.

That aside, the growth of the characters is quite well done throughout the season. The pacing is a bit slow, and its not particularly exciting in every episode, so might not be everyone's cup of tea. It also offers pockets of wisdom sprinkled about.

If you enjoy political settings with a captivating story, multiple character involvement in the plot and character growth, this is for you. I personally really enjoyed it.
