This is definitely a soft core book so don't be surprised once you start reading it. Currently there are only 5 volumes released in English (volume 6 releases on September 1st). It is actually surprisingly sweet and it took a couple volumes but it seems there is going to be more story development rather than it being purely erotic. The main female character also slowly starts to get some character development as she learns to be more confident in herself. There are parts where some characters are childish, but it isn't overwhelming. The art style is also very pretty, Yumi Hisawa-sensei did a wonderful job in creating this series. I picked up the series by chance and could not put it down. I say if you are undecided on what you'd like to read next, this series is something light to pass the time with.
