Wanting to grant Shione's wish without waiting for the next meteor shower, Nonoka and the others decide to make a planetarium for the school's Hokubi Festival, inviting Shione to participate. The next day, Shione decides to visit Noel, who she had also met seven years ago, having previously received a message from her that Nonoka would return to watch the meteor shower with her, though the time she waited led her to become distrustful of her. Shione expresses to Noel how she is afraid of putting her trust in Nonoka again, but Noel gives her some encouragement. Later that night, Shione arrives at the finished planetarium, where Nonoka firmly states her desire of watching a meteor shower with her, with the two making up with each other. However, the next day, after Shione recalls Noel calling herself the saucer, she tells Nonoka that they can't be together.
