I'm seriously debating on whether I should start my manga or not... or which one for that matter... Sorry, not sure if this is the right place to post this...

My most recent idea is somewhat like Fruits Basket, but instead of Chinese Zodiac it's the Astronomical Zodiac and there's no curse (well, unless you call having extremely exaggerated characteristics of the zodiac's personalities a curse...). 13 'main characters' all siblings that live together and a slice of their lives. I haven't yet thought of a name for it nor a constant plot/problem; I'm not even sure if this idea was already thought of.... What I was thinking was have each chapter dedicated to a character and explain a small part of their life... Idk, once again I think it's under developed, but who knows...

What would you guys suggest?
