It was the last day for us to stay together.
I was scheduled to fly to Shanghai, and subsequently to Narita on that day.
Katya was staying one more day in Sanya. The next day, she would fly to Beijing, stay one night there, and fly to Vladivostok.
We walked around the town and left at the airport.
Katya was planning to come to Japan in April to start learning Japanese in a Japanese school in Kofu.
I was busy preparing many bureaucratic forms to get a student visa for her, which was more complicated than the tourist visa to Japan the year before.
I did not feel too sad to leave her because now she was coming to Japan. Instead, I might have felt some responsibility.
