The most amusing twist would be for the story to continue on at the current pace with no timeskip. Just hundreds of chapters of them living their lives separately before finally getting back together.
Honestly I'd be fine with that as long as it's full of crossdressing, but I feel like we might have seen the last. I do kinda hope when Kaoru finally comes back, he shows up crossdressed after discovering he just prefers living that way. Alas, not everyone is as cultured as
Hiura.
