- The first volume/episode, and how. Kō's final line (It's so simple... I just need to cry) is just crushing. The ending song is extremely sad, too, since it's essentially all about Kō and Wakaba's relationship, and, well, yeah.
- And all reminisces by Ko, Aoba, and Akaishi back to "that day/summer," Wakaba, and her last dream.
- Akaishi's 'treasure.'
