This manga is basically happiness fuel. If you are ever feeling down and need something to make you feel better read this story. I've read the whole thing at least 7 times and still enjoy the whole thing. All of the characters are great, with purpose and goals and dreams of their own, stuck by a curse that limits their basic human interaction. If the last few chapters of this manga don't make you overjoyed then i don't really know what will, having character you've seen go through some of the most difficult events in their life only to break out of their pain and find happiness is the best thing ever.
Let me tell you something about Fruits Basket, this manga takes a family and puts a curse on them that makes them transform into animals of the Zodiac every time they touch a person of the opposite sex, which sounds really funny until you realize most of these people just want to live normal lives, and cant.
Even the person who plays God is truly a sad person that just wants to be happy but cant because of this age old curse that wasn't intended to be a curse.
Seeing all these characters work through their problems and overcome their curse is heartwarming and the backstory on the curse that started all of this is my favorite thing in all manga, now i want to go read it again.
And as a side note: never, EVER watch the anime adaptation, it is terrible and stops at the worst point for no reason and gives no satisfying ending to anything
