And then showed no dating whatsoever. The most of a case you could make is for Videl and Gohan. They meet when they go to the same school, Videl suspects him and stalks him, she figures out he saved the world, he teaches her to fly after she got a haircut, they fight in the World Tournament, she gets beaten badly, he gives her a senzu bean and leaves to punish the man responsible, they follow and then Buu shows up a bit later, Gohan is (supposedly) killed, Videl cries and admits she loves him, then they all die and then are revived, he comforts her and then time skip. That is in a way romantic I suppose, but that's the only one that has actually been shown to that detail. The rest follow a general formula.
No relationship - time skip - voila, relationship and a newborn child!
Goku/Chi-Chi - time skip - Marriage and Gohan.
Vegeta/Bulma - time skip - Marriage and Trunks.
Krillin/18 - time skip - Marriage and Marron.
I also like to point out that after the battle with the Shadow Dragons, it was time skip to where Pan has a grandson by the name of Goku Jr. Who did Pan marry? Who marry Pan’s son or daughter? What happen to Pan’s husband? What happen to Goku Jr’s Mon and Dad? Also, why is it that Pan can’t transform into a Super Saiyan, but her grandson can?
I sorry, but GT was just bad from the beginning to the end. I just hope that the new movie we’re getting makes GT non-canon with Dragon Ball Z.
