I liked it, for the most part. Would not recommend it though (unless you like only one plot-line that actually worked throughout a story which is surrounded by filling/mini stories that move the plot forwards only slightly).
I don't think this was originally meant to be more than the first volume (which is jumpy). Because things happen in it that are oddly forgotten (like the first kiss and confession). So after we "continue" the manga there are moments that shouldn't be there. Plus more plot/character depth is added to the story. We go through all the relationship steps with them (again), but his time slowly (a more realistic pacing)... with the added background stories (which are not all bad). The full plot has a lot of good points, which make for an ok read.
I like the main characters and most of the side ones. The main characters change depending on what the plot needs, which most of the time is still something their characters would do, but not always. So when you read those off times they stick out like a sore thumb. And their growth is off, if you ask me. They change (I'll give you that), but growth? Not too sure that's what I'd call it. It feels like the "growth" they do is purely for plot reasons and not for personal ones. Only reason I stuck through it was because I wanted to know more about Akira. He (his back-story) is complex and the main plot centers around him (even if it's told through Takami).
I don't mind the clichés, although there are many. The drama is a drag. So much mini dramas (almost every chapter has some sort of an issue that needs to be worked through, that is resolved within that chapter). Plot has holes, but as a whole it's an ok read. There are a lot of chapters (or rather characters) that are not truly needed to move the plot forward. They feel like fillers. The story has at times that "after school special" feel to it, which is not to my liking.
I think this story would benefit from taking out the romance and making it a story about 2 friends instead. That would have helped a great deal on how people view this manga.
Akira's story is truly interesting (and it's the reason people have chosen 8-9-10 as a rating for this manga). Because the romance is not there for those rating, the whole plot (and plot flow) is not there for those ratings, the character development is not there for those ratings. Akira's plot-line is the reason you read you this manga, and the reason I liked it.
