Even though the plot is kinda heavy. No actually really. It's calming. It's not like in those angst-like mangas where you dwell in those (melo)dramatic moments. Here it's cut before you can only see black. I think the whole manga shows, that for every bad moment there's a possible good outcome. Nothing is completely bad and even if you have the feeling it is, even that feeling can change. Like Amita4ever said: "There's light at the end of a tunnel"
