After seven years away, Ryousuke moves back to his hometown of Shionagi and transfers into a new school mid-summer. He finds his childhood friend Marika, meets Sora—the astronomy club's sole member—and settles into life on the event management committee. Around him, the girls he has come to know are quietly working toward their own futures, and Ryousuke finds himself drawn toward futures of his own. A summer day and the loves it begins, stretching forward toward wherever they lead.
