Simple.  In the real continuity, Ranma thought Ucchan was a boy.  In

this

continuity, Ukyou asked his dad if he could get married to that neat

girl

Ran-chan who kept hanging around.  Only when Ukyou finally catches up

to

'her' for vengeance does he realize they're both guys...

what if they meet during the phoenix pill episode?

Im using this idea in one of my fics. Expect it some time this
millenium. You cant rush genius. Or stupidity.
