Shampoo should go with Mousse.  It is the only logical way to match them 
up.  Ryouga should get Akari, not Ukyou.  I know someone already said this, but 
there is yet any indiction from Ranma 1/2 that shows they even like each other. 
Just because 99 out of 100 Ranma fanfic author writes story about Ryouga 
marrying Ukyou doesn't mean it is true.  Ukyou may go with Konatsu or she may be 
single for the rest of her life.  It's your call.  Ukyou will not suit Ryouga.  
Akari is patient and will accept whatever problem Ryouga has.

	A lot of the fanfics that hook up Ukyou with Ryouga were
written before the character of Akari was introduced in the manga --

That's when mine was started... Before Akari was even invented... -_-
But even I knew they wouldn't pair up normally, so... insert love potion!

or before the authors had any chance to see manga issues with Akari in
them.  At that time, the biggest justification for matching Ukyou and
Ryouga up was simple process of elimination.  Takahashi-sensei may
have realized this and created Akari for that reason.

True, true...

Kun-chan...
