Pretty interesting seeing people applying burgerland standards and calling Midori a pedo before anything even happened. And even if it will, it won't be because she's attracted to Haru's childish body. Finally, Haru is clearly smart enough to properly understand what consent is. I really don't see how reading this can make anyone uncomfortable, at least as it is now.
That aside, my hope for this series is that the author will throw us a curveball and have Haru fall in love for Midori, with Midori trying to hold herself back.
