Ok, lets explain my points a bit:
The story is one I hadn't encountered in either manga or anime yet, it keeps on amazing me what happens and it doesn't grow old at all.
You can't get perfect but this is more than good enough.
How the characters unfold is quite something but we still have to see something from quite a few people, so far it has been limited to hikari and kei, while they sometimes talk about a person's past, it always ends up getting connected to hikari or kei(often its both)
It will make you laugh
It will make you say: aaww so cute, aww so nice,..(you
get the picture..)
It will make you doubt if you have studied enough.. and what on earth is a decent grade these days(realy, it does)
This is one of those that I never get tired of, I have read other works from this author and this one is the best(not that he has even a few..more like 1 or 2 but still)
If you like or don't like this style, I don't care, just give it a try. Its unique ^_^
