The art exhibition has begun again. Shūji thinks back to when Hagu decided not to submit her paintings in the previous art exhibition. Shūji tells Hagu of when he went to an art exhibition and purchased a postcard of a painting of the moonlight reflected on the sea. It reminded him of how Rika's husband died and how Rika got severely injured on the beach under the moonlight. Shūji reminisces about his feelings for Rika. Takumi goes on a train with Rika to Sapporo, surprising her. After they both take a shower, they both go to sleep for the night. Once they have arrived, Takumi and Rika drive north to a barren land. Rika visits her father's gravestone, then she visits her dog's gravestone. She thanks Takumi for coming with her to Sapporo. Rika tries to sneak out of the hotel, making Takumi angry, but then he begins to sob, not wanting to lose sight of her. Takumi goes on an airplane back to Tokyo, while Rika goes on an airplane to Spain. At the Harada Design Office, Takumi noticed that the hotel room in Spain had two bedrooms, one for Takumi and one for Rika.
