However, soon Tohru discovers that there's much more to the Sohma family than meets the eye. Though shocked and surprised, Tohru promises to keep their secrets; but will the Sohma family approve of an outsider knowing who they really are?
Fruits Basket is a later work of Phantom Dream's mangaka, and is better in basically every way. The characters have far more depth, the romance is more believable, and the story is far more interesting and easy to follow. If you liked Phantom Dream, try out the far superior Fruits Basket which, while having a more comedic tone at times, has similar themes and tones and is just flat out better.
