After their final exams, Yoshino and Kirishima head to Yokohama to meet Yoshino's cousin, Tsubaki Akashigata, who recently moved from Kyoto. Reuniting after a long time, the three—Yoshino, Tsubaki, and Kirishima, who tagged along—explore the city together. They enjoy reminiscing and chatting about trivial things as they stroll through Yokohama. However, their fun is interrupted when Yoshino gets a call from school and has to leave, leaving the other two behind. Kirishima seizes the moment and invites Tsubaki on a casual date. Alone together, they find themselves inside the glowing Ferris wheel at night. In this private, quiet space, Kirishima turns to Tsubaki and asks her an important question.
