I gave this an overall 8.

The story is really good and I really enjoyed it. It is very ecchi, with a lot of humor. To be honest i don't understand why this is a One-Shot and didn't get serialized.
The characters are very like-able and the main male character kind of gets on your nerves but all in all they are good.
The art also in this manga is very well done.

I hoped this review helped you in anyway, and thank you for also taking the time to read it.
