I am sorry that you feel that way. I personally do know some couples with a large age gap, and are doing just fine. If you are not comfortable with it, then maybe those are just the kinds of stories and arts that you should avoid/not read. I also personally do not like the GT series... I avoid that too, lol.
So, my imagination is more inclined to think how the DBZ Pan would have turned out.
I do not like certain other ships, but I/we have to understand that people are different, and will like different things. We just need to learn some tolerance, because, like I said, people will just choose to like whatever they like.
