Both Prabhat and Surya are school going boys with very different perspectives. Prabhat was a boy obsessed with winning.
He would only play a game if he was good at it and knew that he would win.
Further, he did not know how to accept defeat and even prepared for a friendly game with complete seriousness. When he realised that he would not win the friendly game, he cheated to win.
In contrast, Surya was joyous boy who did not care for winning or losing. While preparing for the friendly match, he was relaxed and joked with everybody. Even during the game, he was not paying his complete attention and lost. However, he was not sad about it.
He in fact told Prabhat that he would like to play with Prabhat.
Concluding, Surya displays true sportsmanship that is lacking in Prabhat.
