After reading "Transitions" (thanks Richard) I had an idea for a sadfic.
As usual, I don't have the time to try this myself.  

Assume that Ranma and Akane don't marry while in high school and that after
graduation Akane goes to college but Ranma goes off elsewhere, perhaps to
study other martial arts in places like Malaysia, Indonesia, Philipines,
Brazil.  My idea is a series of letters from Akane to Ranma, slowly changing
in tone until the last one, a "Dear Ranma" letter ("Dear Ranma" would make a
good titlefor this).

The sadfics based on AMG, Ranma, Nuku-Nuku show the fine line between comedy
and tragedy.  Consider how easily Romeo and Juliet could become a comedy,
and how equally easily most of Will's comedies could be turned to tragedy.
Something to consider.
