Now that I'm done rereading the entire thing … this really was part of the mosaic series that started two chapters ago, huh. Their takes suddenly felt a lot more ominous with a lot of undercurrents in how they treated each other. All the snowballing that had been hinted were paying off one by one.
It's especially delightful because I don't think the manga addressed Jin-ran's sense of inferiority towards Ibuki this seriously before (Scene I), given that she fell for Kanade who was in love with Ibuki, or how Botan felt about the fact that she was aware of Kanade's feelings for Ibuki since Chapter 3 but still ended up snatching Ibuki for herself anyway (Scene II).
It's pretty noticeable from the buildup towards when Botan and Ibuki nearly had their first fight as a couple, but this manga really relied a lot on the unspoken things because that adds a lot of weight for when things finally got spoken out loud.
I want to see where this goes next.
