WARNING: If you truly have nothing else to read, it's a 2.4 out of 10.0 type of manga.
The panels are exceedingly stiff outside of fanservice, the theme is only consistent if you're not keeping track of the setting or dialogue (the hero literally sets out wearing a back shaped like a children's red bag from primary school, among other things), and the characters are all intentional stereotypes of doujin characters even without the ultimate goal of "get knocked up, bring the hero home" for all the female companions. The Protagonist is also very explicitly the worst kind, the Oblivious Hero, played so straight you would think the closet was made of transparent cookie sheet paper held up by used floss strings and a prayer to the Gods of Celibacy.
One of these days, someone with better writing skill or more courage to dive straight into porn might redux this, because it does have potential--but as for right now, it's bog-standard slop with no real appeal to anyone but the desperate or overly horny.
