Mmm...to break-up Akane and Ranma, reasonably and completely...I doubt it.
Not only will he/she not forget everything he or she had done for each
other, they respect each other too much, not like how Ranma sees his other
fiancee.  [Insults doesn't really matter to each of them.  The respect I
mean here is the same like you look up to your parents, that kind of love
and respect.  No matter what they tell you, hurt you, and such...you'll
always be there...as much as Ranma has always been there for Akane, and
Akane for him.]

By this reasoning, Ranma is in love with Ryouga.
