I'm sure other people will get you on grammar and context and such. I want
to get more into your story.
First, Ranma having sex with somebody in his past is pretty far fetched, but
not impossible. I do hope you plan on going more into detail on how these
events unfolded. I think you can touch a lot of emotional chords here,
unless your going for a "Big Daddy" story line. Overall, I liked reading it
and I thought you have something solid to work on. You might want to get
the characters more emotional involved. Tensions are high because of this
and I don't think your quiet brought it out. I also look forward to hearing
how the other Ranma characters react to this. You got something and I hope
you keep with it.
