I read a little of Midori Days before. I didn't really like it but that's because I didn't find it that unique except for that little predicament. It kind of bored me. Maybe I'll give it another try.

One manga I'm not exactly recommending, but more like introducing, is Hot Gimmick. (Find it on onemanga)
I read it because people said it was good but the ending kinda made me mad. The characters pissed me off a lot too. XD

Pros: Story line flows smoothly and is easy to follow up. And the art is pretty good, not the best IMO, I like the cover pictures better. And uh, you might find more pros about this manga if you enjoyed it more. I thought it was okay.........

Cons: You'll either like the characters or hate them. There's only black and white. No grey.

Btw, I'm looking for a place where I can read Azumang Daioh besides manga hut. Any suggestions?
