[edited] I have revisited this manga recently and I found it considerably more enjoyable this time around. The problems I had with it previously are still there, but I think there is definitely something to be said for the way emotion is conveyed and for the writing style. It's far from perfect, but I've read a lot of utter garbage lately and this is not it. The second story is also quite good.
Like others have mentioned, the weird little comical faces thrown into the first story were extremely unfitting and weird.
Attempted murder plus ADORABLE COMEDY!!....wait what? It didn't work for me.
. Ryou is borderline mentally handicapped. Maybe "borderline" is being generous. I really didn't mind that the relationship was completely horrible, but I wish it had ONLY been serious. The first chapter has about a volume's worth of drama, and the second is normally paced and just very day to day lives of a relationship with someone who probably should have a legal custodian. It's weird for one chapter to have SO much and the next to be all normal rainbows and sunshine.
Aside from the various downfalls of the story, the paneling was frantic and sometimes difficult to follow. The art, however, was very, very good. Really gorgeous. My rating is as high as it is because of this and because the sex scenes are pretty lovely. heh.
I enjoyed the second story much more than the first. It was pretty cute(and hot). The story felt new, though I can't really place why it did as going through it in my head, it's nothing ground breaking. Either way, it wasn't stale. Worth a read.
The oneshot didn't really work for me, but I can't place why. The characters weren't particularly likeable, the story had an odd flow, it just wasn't my favorite.
