Oki, it might seem I have overated this manga a tiny bit. But I truly believe this was one touching story. I was crying through the whole of the last chapters. Story. Basically, its about this girl {20 years old} who was in an accident 1 year ago, and one of her blood donors somehow "transfered" part of her soul into the girl {Maiko} while donating her blood. One day, this teacher {her main love interest throughout the story} starts at her school, and she has to have these weird "visions" about a younger him... and so it goes on and on. There are some twists tothe story though, which I found throughoutly enjoyable, and shocking. It really focuses on the sacrifices you have to make to make yourself, but above all, others, happy.

Art.
I really liked the art. Dont know exactly how to describe it though? It looks very appealing ^^!. hehe.

Character.
I loved all the characters, and the differences and contrasts in them. Touja-kun is one of my personal faveorite, although he's only 3 years old. The character developments happen quickly, yet gradually, as there are many "buts" and "ifs" but they all end up to be characters you will love.

Enjoyment.
As I already pointed out; this made me cry- so that's a good point in my book. Its very emotional; and is therefore enjoyable in that aspect.
