Sure, humans are illogical or rather irrational in lots of ways, but there is still a difference between writing a protagonist in a human way and writing them to behave like the usual incoherent pseudo humanized drama character tropes.
Here you have the latter. Specifically, the overprotective childhood friend who clings too much, because she is insecure and still childish herself. And the anxious childhood friend, who grew up to be really hot, but is still childish, yet tries to behave more like an adult. Sprinkle in some yuri tropes and wOw, WhAt A mAtUrE mAnGa
It is about as human or mature as any random daytime television soap drama, which have been recycling the same old crappy storylines amd characters for the last 40(?) years.
