A stagnant manga about an ordinary boy's growth.
This is so ordinary in the way it flows, kinda like most seinen, only more plain somehow (and it's even lampshaded in the manga itself).

It's acceptable basically, but I give salute to one thing. Most of all was its guts, using the narrative technique to show something other manga didn't use (or clouded it with a cloud of pretty sparkles, dramatic backstabbings and fiery passions); anticlimactic changes. To everyone. Within the limited vision of the protagonist, it adds a very sense of poignancy. People slipped in and out through the protagonist's life. People prevalent and important in first volume wasn't even mentioned in the future, etc. The same as events that, in other manga, would be depicted with the hottest dramatic impact.
Everyone came in, came out, came back in, rarely told, rarely missed, rarely remembered until when it's convenient. Sure, totally dramatic for the protagonist at that time. Afterwards? Nothing. The manga itself don't make any big deal about it, neither did he. He goes on. Just as how his life is.

In expense of that, however, things get really.......stagnant, I have to say. No, not that it's not growing, or that nothing really happened. It's just nothing FEELS like happening. In these 6 volumes, there aren't any single dramatic change within the storyline. Even as his condition in life changed, nothing has really changed.
It's realistic and very life-like, but OTOH, his condition in life wasn't very good since the beginning, so all in all it's kinda high-strung in terms of teenage angst, and there aren't any significant change to change the mood. And after 6 volumes, it could be tiring. It is, IMO.
Then there's the 'in and out' thing; in reality, this seems very important. In fiction tho, this seems like a unending storm of plot devices, entered only to create some unnecessary dramas at the moment. Everyone feels unimportant. And after some cycles of that, I myself began to wonder when will it end.
And mostly I find it bizarrely realistic that people the protagonist had seen the most in his life were people with the most personality in the first sight, while the girlfriend seems very flat in surface. Ordinary seinen trope, but a very enigmatic case because of its selfish implication.
In the end, still a solid read, but not for the narrative value.
