Interesting detail I found after re-reading chapter 6.5 (the mention of the lozenge was a hint from the author to do this, I think):
Seno's line to Nekozane on page 7 of this chapter, "The breeze here is nice and cool. It's much better to sit out here than in the classroom" is almost identical to what Nekozane (anonymously) said to console Seno in chapter 6.5. In the Japanese raw, the lines are just as similar.
