Neither of the two major bloggers covering the manga said anything about any reactions - either by Chihaya or the other spectators.

Well...on the very first page after that first scene, we're told that Chihaya was waiting for the paper delivery "6 years earlier, in Tokyo". (NB: there are 3 years of Junior High and 3 years of Senior High in Japan.) Hence, I would assume that the first scene occurs in Chihaya's final year of school, i.e. about 1.5 years from where the manga is currently at.
