"Contrast Match" (Original) by Weebee
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.
WeeBee has turned this story over to another writer and will be removing it from ff.net when that author has finished his rewrite up to where he has completed to.
