I really enjoyed this story. I bought it based on reviews and I'm glad I did. I've only had it for 1-2 weeks and I've already read it 3 times. I find myself picking it up again almost subconsciously, starting in the middle of one of the volumes and rereading this or that scene...
I feel like it's a simple, understated story that somehow ends up being very touching and, to me, beautiful.
I say 'understated' because in many BL manga that I've read (and manga in general with some sort of romance attached), it seems like many times they're heavy on the narration. When there is a significant event, such as a character realizes he/she loves someone else, most of the time it will straight out say in narration something along the lines of "I love him!" and give all the reasons why. What I really like about Seven Days is it isn't as heavy-handed. There are scenes where there is narration but there are other scenes where there isn't.
If a character realizes he loves someone else, in that page the panels may have no words-- just a progression from far to zooming in, with the entirety of the meaningfulness of that scene in his expression or the non-verbal communication between the two.
They also don't always speak in complete sentences. One character in particular has a tendency to just say what's on his mind, but not the context of it. So he may be thinking about a conversation he had with someone else and make a comment based on that, but the comment itself could seem ambiguous (like "it was just a prank") and without knowing what he's thinking, it could be misleading.
There are a few places where I still am not QUITE sure what they're really saying because they trail off before getting to the specifics but I actually love that about this series. It feels like every time I reread, I understand it a bit more. I was reading too quickly the first time to catch all the subtleties and upon rereading it feels like I notice another meaning to this or that panel. It isn't that the story itself is so deep, but that there are parts that are left a bit to the imagination, and other parts that rely on the reader to understand the characters and connect the dots about what he is really thinking now. It makes it a much more engaging to read.
I have to admit I both love and don't as much love the art. I really like it but there are a few parts where it throws me off a little-- the angles don't seem quite right, inconsistencies in the noses/eyes, their proportions seem off-- but then there's a panel where something hits me as beautifully done, and the women actually look like women and not men in drag-- so overall I don't have any complaints about the art. I think it fits the story.
One thing I like about this story is everyone is human. Some girls only see the surface, some like to tease others. There isn't much thought behind a guy with a guy vs a guy with a girl-- the characters just think in terms of love or like and don't even think to question anything else. And if the story starts out saying a character acts a particular way, it later shows that character acting that way naturally so it makes it feel more realistic.
I really wish there was more to this. I would have loved to read another 7 days, 7 weeks, 7 years-- even 7 more hours in their lives. It's a very nice story about people getting together but if you like to read about characters once they are together, it leaves off before you get to explore that much at all, sadly. I'll hold out hope that magically some day there will be more to read with these two...
