Okay, Kabura friends are an epitome of shit, seriously.
Guess the "love" requirement is deep friendship unless Kabura really loved Haru/Nazuna...
Still, why is Kabura her "superior", Haru/Nazuna seems to be more rational than current self, she planned to turn Kabura if things go worse.
Well in the end, really happy with Kabura being healthy again, obviously, after years of struggling it's well earned. But her stealing other people partners, ugh...
