So far, there are only 10 chapters of the manga, I've read them all and hence I am writing this review. First off, there is a LOT of ecchi, and to say the truth I am not a fun of ecchi, but if you are, you might find this manga interesting. Kazushi is a virgin and interacts with other-worlders as per his father's orders. He has a younger sister with a bro-con. Leaving all that aside, this is Harem manga with so many girls arounf the protagonist but he still fails to lose his virginity, This manga has bits of comedy (The last panel of the 10th chapter reallymade me laugh)
But overall this could be considered 'softcore you-know-what'
