Mr. Naka is my friend.

My friend, Nakano, lives in Tokyo.

Nakamori is my best friend.

He is my precious companion.

She was standing in the center of the room.

In the midst of studying for his exams, he chose to go out and play with his friends.

I think his Japanese has improved quite a bit, hasn't it?

I am busy with work during the daytime.
