Ok, I'll try again. I read a Ranma 1/2 fanfiction once that paired Ryoga with Nabiki. I thought it did a very good job of putting the two together and then exploring the evolution of their relationship. The only reason they got together was some kind of pag-ibig potion that went wrong, and after it wore off, they were already used to going out so they just went with it without realizing they had been affected sa pamamagitan ng a potion. Oh the amount of trouble Ryoga got into when Nabiki found out he was P-chan.
The tagahanga fiction was Furinken Summer, which I had printed out and read in college some 15 years ago. Still have the printed copy. link
