Hey, bringing out to you the manga from which the anime came from (d'uh).
Anyways I'm one of the people who've watched the anime B Gata H Kei, who thought that it was an ok show, nothing special. The reason I started reading was just because I wanted to know how far the relationship between the main characters is.
So I ended up looking for the chapter where the anime finished but couldn't find it so I started reading the whole thing since an early chapter (20 or so) which in the end wasn't a bad idea since I almost forgot everything about the story and some of the scenes are worth reading because they were censored in the anime.
Now, don't missunderstand me, B Gata H Kei is far from being an ecchi manga. The ecchiness in it is pretty low, but it's true that the characters talk about sex 90% of the time which can be a turn on for some people, and a relief when "it" actually happens.
What I enjoy the most in B Gata H Kei is the main character Yamada. A beauty tsundere, self-proclaimed slut, whose aim is to get 100 sex partners. That's how she's introduced. But as you read on, you'll discover that she can be a really amusing, clumsy girl, annoying at times(ohyea), but very cute when embarassed, especially later on with Kosuda: (main male protagonist)
image: I don't know how it's called but it's one of those mangas where you read first top to bottom then right to left (like K-ON!).
Thing you might not like is how slow the pace is. There are so many times you think it's finally gonna happen when it actually doesn't, its teasing is painfull.
But let's say it's for the sake of development which isn't a bad thing.
There are currently 97 chapters which are composed of other small chapters (that's how it is on mangareader at least).
To conclude, B Gata H Kei is really a fun read, I surprised myself laughing at times. You don't wanna read everything in one go though. Keep a slow pace, if you get bored, just do something else in the meantime, don't worry you'll get back on it ;).
People who wanna start over where the anime ended... Well I can suggest you to start at chapter 84.
