Well, I guess, of those not mentioned, and depending on exactly how you define it, would the below apply?

http://www.fanfiction.net/u/231396/Note1: In 'Awkward Consequences', it is 'Ranko' she is on friendly terms with, not Ranma, that is an important distinction.
Note2: In 'Love's Rebirth', it is more a past rememberance of a romance, since the story has not been continued, and is likely dead, it is uncertain what would have occured in future chapters.
Most of the Uncles Bet Stories would also apply I guess.
