Please stop. It's 20 goddam 24, can we just bury the 'but we're both girls' trope? Enough.
I'm starting to use this trope as an early litmus test for whether I can expect the manga to have good writing.
Add failing this litmus test to the suddenly wtf pacing and I've now greatly lowered my expectations for this one.
I don't see the problem with the "but we're both girls" trope itself. Some of us are kind of slow when it comes to what we're all about. If you figured yourself out when you were young, I'm happy for you, but not everybody is that self-aware.
That said, the pacing in this story is absolute shite.
