saying this is a great series is probably an understatement.
this is a wicked series, one of the best i've seen recently. the characters are realistic and well-portrayed, the story moves along at a good pace.the romance isn't over-the-top, and the sporting action is very good. one can sympathise with and relate to the emotions, feelings and reactions of the main character due to its very accurate portrayal of school scenarios. all in all a close-to-perfect shonen manga.
i don't know why people have said this is like love hina - when watching the anime anyway, the feeling is totally different. i have read the love hina manga and watched the anime quite a few times and i did not even get the idea of a relation until i saw it mentioned here. in technical terms the scenario is the somewhat similar, but when watching the anime anyway it doesn't feel at all even close.
and finally, i don't know why everyone is calling the main character yamoto 'stupid', 'a retard' and 'a loser'. i completely disagree - in fact, this was one of the first series (in anime anyway) that i was thinking the main character is not the stereotypical loser of romance mangas - he is good-looking, athletic and pretty popular. its very refreshing to have a character liek this for a change - the almost exact opposite of the loser that the comments here describe.
this series is definately worth the 10/10 i give it. HIGHLY RECOMMENDED
