>>123900721I think narrative wise there are just a handful of ways a GB story can go, at least as shown by the west.
>Character learns a lesson about the other sex.>Character becomes friends with his crush thanks to the GB.>Comedy about the guy turn girl having to learn how to be a girl. The few times where they break the mold is where they add the GB stuff as a twist on the another story formula. Like Jekyll and Hyde but with Hyde being a woman or some kind of thriller where the character getting GB helps them infiltrate a place or learn about the real culprit.
>pre-emptively GenderswappedNot sure what does that mean. However lets take Japan since they are the ones who make GB manga the most.
I can think in three long running Mangas where the main character gets GB for most of the story and all of them play it for comedy, either by getting into misunderstandings or by Shenanigans but in those story the GB is almost incidental, the main issue is not getting back to normal but some other thing.
