He WANTS to fight him yes. But he isn't doing so. At least not yet. As said, he thinks rationally about the situation and realised right away that he would only push Xia YuNing away. Even with the latest chapter, with Ye XingHe's unreasonable request he decides to go along.
So definitely a different kind of "rival", for a change. :)

True, at least he knows how to control himself, and use reason. I have a feeling thought that the two of them will fight, and become good friends. At least I hope so, since Ye XingHe doesn't have a Vegeta to his Goku, there's that kid from the early chapters, but I don't really think he fits the bill.
Wow, a love rival of sorts that doesn't resort to the age ol' "Imma beat you up punk! That's ma gurl!", and actually thinks rationally about how to win her back.
