Yeah, I imagine it doesn’t matter much to either of them what Haruka’s hair actually looks like (because yeah, it’s absolutely a horrible patchy cut), just that there’s something right about it being short. Though I have to admit I just pin a lot of my hair feelings on Haruka since I wasn’t allowed to cut my hair short until I was 17, and even then it was less that I was allowed and more that I could drive to get it done alone.
And haha, it was fun to write little Michiru because she lacks the self-awareness about her snobbery I see her having later. She’s at the age where what she’s able to do matters more than why she can do it.
