I guess the conclusion is that Sabu just struggles with storytelling.
I think the short pieces and elements of the series show that she can do individual scenes quite well, her character conceptions aren’t uninteresting, and she can be very good at comedy. (This is in addition to the art itself, which is uneven in quality but pretty expressive at its best).
But Citrus is a great example of a story with a splashy and intriguing premise that presents an apparently unresolvable problem, but the author ultimately has no real idea how to resolve it.
The Dynasty forum featured months and months of readers’ meticulously detailed speculations about how the various plot obstacles (the school, the fiancé, family, etc.) could potentially be overcome, but ultimately none of the theories panned out because all the conflicts that had been built up over the whole series were handwaved away in a single page of silent panels.
I don’t know why a writer would set themselves a task like that without having some idea how to eventually complete it (“the absent dad saves the day,” “the mom and the grandpa knew all along and were working together to make it OK,” whatever—just something).
But like I said—creating art of any kind is never easy, and sometimes things just go off the rails.
