Our heroine Yoshimoto Ai recalls meeting a random guy during tanabata while watching the stars on a hill at her inaka. When her school year starts up once more in September, the guy she met, Inafuna Takashi, transfers into her class. He apparently wanted to get the best view of the starry sky, and so he moved in with his uncle, the village chief, to the middle of bumblefuck. As she goes to watch the stars with Takashi again, she realizes that it would be a great idea if all of them could go watch them together. She then decides to form an astronomy club with her classmates (also her childhood friends) for some last memories, because the school is getting torn down the following year.
