I've always liked the odd teenage love story, you know, between the child friends age, but before the age about 17 or so, when you come of age and everything becomes a bit more serious. Sweet, harmless, perhaps not particularly interesting, but it gives the characters some happiness every now and again. I've just finished watching The Wonder Years on ITV 3 and whilst Jai and Annie aren't a scratch on Kevin and Winnie, it's the kind of young love storyline I'm talking about. (Winvin? Kennie?)
It would be nice if they had found their "soulmates" young and they go through their time on the show together and they leave/marry at the end of. I actually believe that writers put too much time into make their popular pairings too tumultuous - not that I'd put "Jannie" at that level yet.
