Again, we must take in the fact that this is a hentai anime. All hentai puts sex on high priority and often, they do it in every two scenes if not in every scene. Most of the hentai basically has no plotline and if it does, you forget about it because of the sex. The presentation of Kao no Nai Tsuki makes sure that you don't forget the actual story. The characters personalities are very enjoyable to watch. Suzuna the main character has a very strong personality and doesn't give in to sex to the guy Hayama Kouichi as easily as those normal hentai female characters. There are a few scenes that made me laugh and it was pretty different from what I expected. It really wasn't the
"Hey baby, let me fuck you" and
"Okay."
type of thing. She actually resisted...

This series has quickly become my favorite hentai series of all time, no other series comes even close to Kao no Nai Tsuki. Not many hentai series are able to combine humor, drama, and romance as well as this.

The evolution of Suzuna's and Kouichi's relationship was done well (for a hentai series anyway). I found it amusing whenever Suzuna would slap around Kouichi, though I did feel pity for the guy at times. I don't know if a romance would even develop between these two in real life though after watching some of the events that happened between them, but I still enjoyed watching their relationship grow.

Suzuna's relationship with her maid, Tomomi was also touched upon as well a little, I just wish it was given a bit more screentime to show it evolve a little more.
