In fact in the new lore, Hayabusa said to kagura that she's nothing more but like his younger sister, and he started to like Hanabi again, and hanzo liked hanabi too, but Hanabi gave up with feelings, she thought they're now useless and she started to focus on being stronger instead of finding love.. also Hanabi cannonical's age is 23.
I shipnkagura and hanzo indisous tutor skin because they both have white hair plus it would make like a cute evil relation ship that annpys hanzo but hanzo loves her at the same time
