first off, you got to be able to bear the art before you can appreciate the manga. its sorta messy and hazy, lack of details but the bright eyes convey emotions well. their faces really beautiful, but everything else is like some unfinished product, sketched done before inking.
or the story itself, overall i think it is quite weak compared to her other works. the first story is very predictable same old same old, but i think the message of the story is just 'do your best'. very japanese-like. i like the girl's character design, it is not often one find very tomboyish looking girl, and she isnt even a tomboy.
second story is quite meandering and go places i dont think it need to go, overly melodramatic and kind of stupid. i wish theres at least a volume with these characters so we can feel just even a bit of empathy for any of them, but for now it feels hollow.
third story is the best, because i'm just a sucker for stalker romance. i really like the ending, and the guy deserve hellish end for what he did so carelessly that he ruin a lot of other people life. that's what you get for being careless and self-serving.
all in all, this is not her best work and you should read this only to satisfy your love for her works.
