I had forgotten how important the theme of "being yourself"/self acceptance was. Or more like, I never really thought about it. It was always there, but it felt like an obvious moral, so nothing new, but to see it brought up again, in such a context is interesting. It's nice that Mei is reminding Yuzu of the same line of thought/values that she has been following pretty much since ever, even before she started pursuing Mei, though a little absentmindedly. It's always nice to see Mei emotionally support Yuzu, with how focused and helpful Yuzu has always tried to be for her.
Iirc, Yuzu had self doubt during the presidency/delinquency arc too? Ofc, she's always had her moments of insecurity here and there, but ultimately, she always seemed to face things head on, whether she had really (or more or less) thought them through or was just braving them. She's such a kind, compassionate girl, seeing her rely on others is heartwarming.
