Woah!!! What a great manga!
The art is a bit jarring at first, but when you get used to it, you'll have an amazing experience.
I absolutely love how Kurosawa has grown both as a character and as a person. You can hate him in the early chapters but you have to agree that he is really well-written, with lots of depth.
And then, there's the really unexpected love interest, Sugawa (the yankee girl). All I can say is that I would have appreciated it if we got to see more of her, and how both of them got closer, and also some fluff chapters.
Overall, it's a great series but it could have been a bit more longer. 9/10
