"Contrast Match" (Rewrite) by Sinokaze
There's no Michiru, and Ranma gets on with his/her life and finds a certain motorcycle racer. Fun start, and has a good slow-building pace. Worth a read.
This is a rewrite/takeover of Weebee's story of the same name, with permission. Weebee stated plans to remove his version when this one caught up.
