The best chapter of the series so far. The tension of realizing one's own feelings and coming to terms with that paired with someone sharing the same feelings but attempting to repress them is so strong. The doughnut metaphor is perfect, displaying both Shion's and Michiru's feelings and how they are responding to them. The best part is getting to see Shion verbalize exactly what she told herself for however long she's loved Kiki and hating herself for it.
Such good drama and emotions really bring a story to life at times like these.
