Pavel Zubov (Aleksandr Mikhajlov) lives and works in arctic Nikel. He came there thirteen years ago, just after the army, without even a glance at the road leading to his native village, where his bride Nastya was waiting for him.

That is why he did not come back home and stayed to work in the North. Read more on Wikipedia.
