Genre: Crime

The semi-criminal group holding grudges against Yoshino and Kirishima, along with Azami Suou, had gathered under Ozu’s command. While Kirishima was with Nao, Yoshino spotted Ozu and his group and decided to carry out a plan on her own. Upon learning about Yoshino’s situation, Kirishima reluctantly contacted Shoma, the only person he could turn to in Osaka, to entrust Nao to him and head toward Yoshino. During this time, Kirishima called Yoshino, and the two made a significant "bet."

Returning to Japan after living abroad, Nao Shioda lands a job as a TV announcer. She crosses paths with Kirishima, her ex-boyfriend from the past. In front of their friends, the two pretend to be strangers, but when they find themselves alone, Kirishima gently speaks to Nao and hands her his contact information.

Meanwhile, Yoshino and Kirishima travel to Osaka. While there, Yoshino reconnects with Shoma after a long time apart. Coincidentally, Nao also arrives in Osaka to attend an event, setting the stage for their paths to cross once more.

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.
