One of your posts suggests that you have read it though...<-<
I dropped this one after the fifth volume. If you're a fan of harem, by all means read it: if you've read one you've read them all. I only dropped it because it followed all those damn harem cliches. I think I only enjoyed the first three volumes. XD Unlike other harems, the male lead here was pretty decent...well, until he started getting cliche...
As mattai said, there isn't much of a story after like the third volume... it's all repetitive, no development at all. ~.~
Country bumpkin guy goes to dojo in the city, meets girls, ecchi and misunderstanding ensues, girls fall for guy. "Evil" girl appears to challenge guy and dojo girls, guy beats her and does a "power of friendship" speech, evil girl falls in love with him too, rinse and repeat this last part about 3 or 4 times with the odd evil dude entering the fray and becoming friends with guy (instead of falling for him.) Manga ends with the latest evil girl falling for guy (no surprise) and none of his supposed harem has confessed to him. That's it.
A pretty shit manga imo. Even for your typical harem series this one is pathetic.
