The relationship between Ichigo and Orihime mirrors Kubo and Ichihime fans.
Kubo barely puts in effort while Ichihime fans act like Orihime and submissively accept the little crumbs here and there.

Meanwhile Ichigo and Rukia mirrors something else. Kubo will do something and if he half asses it then Ichiruki fans will call him out on his bullshit. They're also more proactive and loud.
