Meeting a friend after a long time at Osaka

I'm in Osaka now. Business trip again.
I meet my friend who lives this area last night after a long time. He lived in Tokyo but moved to here because he joined a company that was located here.

Probably I met him for the first time in a year. When he lived in Tokyo, he was a graduate student, and he got a Ph.D. then joined the present company. He looked more adult than ever. I wonder because he isn't a student now.

Today's my working place is Kyoto. I move to Kyoto from now.
