Well i read it so For what i understand throught the pictures, it's after everyone has gratuated since everybody go the cultural festival of the school in casual cloths. We see that Doujima and Akari seem to be close. We have a discussion between Maki and Yuu, probably about the relation between Yuu and Touko. Forget to mention that Yuu and her sister talk at the beginning of the chapter. Return to the festival,everyone go to watch a play and Touko is late. Yuu go to found her and they both watch the play standing next to the wall. After that Yuu, Touko and Sayaka goes to the cafe to discuss and judging by Yuu's reaction, they talking about Sayaka's confession which embarassed both Sayaka and Touko. After that Yuu and Touko go foa walk just the two of them and probably talk about everything and stop on the bridge near the littles stones in the river where Yuu confessed. We also found that Yuu had a ring on her left ring finger, which probably mean what you think. The 2 last pages are in colors, last page is them from the back walking han in hand.
A very wholesome chapter to end a masterpiece.
