...Tae to realize that Yuki's affections for her (respect, replacement mother figure, etc) are fundamentally different from how Mai likes her.
I'm fairly certain that she's aware of it to some degree, but is still stuck in the "is this a crime? am I a criminal? oh no she's hot; I'm going to jail!" phase to actually process anything, but I'd also like a development like that. Honestly, in a way, so long as it happens as organically as things have been developing thus far, I'm all for it.
Though we don't know yet just how Yuki's newfound affection will fully manifest, and this could be a very amusing can of worms in itself and I'm excited to see it opened.
Thinking about it... there is Mai's perspective to explore, it's obvious that she's a girl in love, but she's completely clueless at this point, so maybe if the series explores that first then there's something to work with. Though something tells me that this would be kept as an "escape avenue" if the series gets axed or gets close to ending.
Ikenai Otona?
Yes, that's the one. I genuinely love it, it's a great read.
