Why don't Wukong and Bulma have the feelings of Wukong and Bulma?

The old bird has long said that Wukong and Bulma are not suitable. (At that time, some viewers suggested that it was rejected by the old bird. ) Wukong is a "fool". Although Vegeta is almost the same, at least as a prince, he can be arrogant and scheming. Besides, the old bird means that at the beginning of the Dragon Ball ending, Bulma was only Goku's friend and Leping's girlfriend. Because Wukong is too stupid to even touch love, only Kiki who is inexplicably engaged will post it upside down.

In Z, out of Vegeta's popularity is too high, let him replace Leping with low popularity.

After all, Wukong doesn't understand such things as love. I think he and Kiki are more family than love. They are a family, but they may not be as good as Vegeta in love. There is also popularity and the author's ideas. The old bird didn't want to betroth Bulma to Wukong at first.

After all, two people have different mentality, one is martial, and the other is a businessman (Vegeta is a little scheming, although proud, but he is better than Wukong in family and decision-making). Also, when Wu Chi can marry Bulma, Wukong is already married.
