Ash is more interested in Pokémon than romantic relationships (something he and I both have in common) and I like it that way. I like being able to watch something without there having to be some sort of romance because I really don't like it, not just because I don't quite understand it. And besides, it is designed for children so even if there were to be romance it would be childish and played for laughs, and probably wouldn't last long either. So both in and out of the show, I highly doubt there'd ever be serious romance.
