I wrote this assuming you read the description!

I gave this series a 10 in almost every category (the category that I didn't was art, because it was admittedly unimpressive at the beginning, but it does improve). It is my favorite story of all time. It doesn't matter if you bring me novels, animes, comics, cartoons, movies, or anything else, because I'm sure this series will rein supreme.

From the outside it looks like your average shoujo series: cute, optimistic, orphan girl living in bishi heaven and knowing something secret about them. But it's not! Natsuki Takaya writes characters that really take flight into a life of they're own. No character is perfect (even miss-goody-two-shoes main character has a few dark secrets).
The "curse" that the family who's lap she's fallen into is under is no laughing matter. Essentially the curse is simply a social setting within the family, only that the members of this social circle turn into the members of the chinese zodiac (as well as the cat) when they are hugged or bumped into by a member of the opisite sex. As the series goes forward this seemingly silly curse becomes something of dark nature and you see that the people living under this curse have had to give up so much, including love, family, memories, and hope.
You see through the eyes of every character from the main characters deceased mother to the head of "Prince Yuki Fan Club". This continuous switching of perspective makes it impossible to hate any character completely for the mangaka always seems to be making you sympathize with them.

Yet the series stays lighthearted. It's sweet, cute and hilarious in the weirdest ways. If you give this series a try i can garuntee you'll never regret it!
