This view is like a sentimental, rainy day good bye scene in the movie. However, it is not a movie, but a real life moment. The rain makes the good bye scene more sentimental. In spite of the rain, the boy is bidding good bye to someone on the train, at the window. Another boy carrying umbrella is standing at the other rail track, hunching. The emptiness of the space other than the two boys might give one a feel of loneliness.
