Takako Hara (Yuka) and Kotaro Ozu (Takahiro Miura) who came to Miyazaki alone on Takako's birthday, shaking off the surroundings. In Miyazaki, Takako and Kotaro visited a shrine of memories before Kotaro's family divorced, and prayed for their future there.
'I can't run away. I chose it myself, so I'll keep going.'-Takako tells herself, but it was a painful reality to wait for the two to return to Tokyo. Kotaro has a dinner with his fiancé Kaori (Mayuko Kawakita). Takako had her own birthday party where her Egawa (Hirofumi Arai) was supposed to come. Escape from both sides became a well-known fact, and it was known not only to the staff room but also to the students. 'Elopement' Takako and Kotaro are whispered by the students. The principal pays close attention, and her colleague's teacher even says, 'I'm upset the students, so I think we should take responsibility.'

'I tried to put someone in the way I wanted, so no one could choose.' --- Realizing that, Takako consolidates one of her determinations.
