10/10 without a doubt. Not only is it original, the catch [being the different colored uniforms] is unbelievably...catchy! Once you start, you're like a fish on a hook who can't get away unless you hurt yourself. If you stop the series half-way to go to sleep, for example, you will crave it once you wake up.
Another thing is that this shoujo manga is about the guys falling for the girl and not vice-versa.
Art:
It's very "shoujo". How big the eyes were and how wide the face can get pretty annoying but it's nothing to fret over. The mini characters that appeared every once in a while were soo cute. ^^ Can't say much about the art.
Characters:
Here's a shoujo manga where the main female character doesn't want a boyfriend. That's rare... "Piyoko" was a hard-headed girl who was determined to turn the whole school into greys while unraveling the contents of Isshiki's heart. She doesn't do it because she likes him as a possible boyfriend, but out of curiosity.
Isshiki is a germaphobe who is fairly detestable. Even after explaining himself, i found him annoying and selfish.
Nishizaki is just Nishizaki. The typical bully who is good-looking and strong.
As for Tetsuta, he's very happy and brought life to the manga. He stole Hina's first kiss, gave her a nickname and fell in love with her. He's an original character that kept things moving.
Overall:
A very funny, unique, addicting manga that is a must read by shoujo lovers.
