Overall, I wouldn't really recommend this manga to anybody!
It's not like it was the WORST thing I've ever read, maybe someone could get a little enjoyment just from reading it to pass the time, but I wouldn't really say it's worth buying or keeping or anything like that.
This story needed a lot more chapters (or even volumes) in order to progress the characters to the extent that it wants to. With only a few chapters to its name, the character progression is LIGHTNING fast, and the drama hits you in an intense wave. A story like this, in my opinion, is better suited to be a slow, agonizing drama where the characters make a concentrated efforts to understand each other, with the payoff being when they finally get together. All of this just happens way, way too fast.
The same is with the little side stories in here. Once you start getting into it, they're already over. Instead of brief vignettes, I would have liked to see these characters developed more slowly. Instead, I feel like I barely know or can relate to the characters. They don't really act like real people because there is simply no time to develop them.
