Yeah I agree! I definitely cried more than once during season three, but the ending made it all ok. And to answer both of your questions, I was actually considering writing based on fruits basket another. I really wanted to explore what the futures (and pasts) of the characters in the current book might be like. And the story follows both the manga and anime. I kind of cherry pick at time which elements of the manga/anime to include, but I try to incorporate both as much as I can.
