Takane receives a message through the local radio as she is listening through her headphones, which tells the residents that the world they are living in is going to end that day. Thereupon she hears the sound of sirens and screaming from outside the window, confirming the credibility of that message. All of a sudden, a voice coming from her headphones becomes audible; a voice that sounds like no other than her own. It first asks if she can hear it, then tries to encourage her survival by telling her that she will make it if she manages to reach a specific hill in time. By then, she would come to understand, but if she was not to hurry, she would disappear.
Takane wakes up from her dream and notices the sound of people preparing for the school festival. She mentally complains about them being noisy and about how she has no interest in it, that everyone is bickering about gossip while having some sense of camaraderie, that the festival's tension is bothersome, and that after it is over, there would be a lot of trash. She also criticizes that she is in a class with two people who have no plans for the culture festival, until her only classmate, a boy named Haruka Kokonose, comes in and greets her. Takane responds quite surprised and embarrassed as he is in nothing but his boxers.
Haruka, who is quite oblivious to the the fact that he is almost naked in front of a girl, explains that he tried to pet a cat by a fountain, but he lost his balance and fell in. Takane, acting flustered from the sight, tells him to put his clothes back on, to which Haruka replies that his clothes have not dried yet. She then attempts to help him put his clothes back on, regardless of them not being dry, until the representative teacher of their class enters the room.
