The joy of the frog was sweet as the nightingale could gather so many people to attend her concert. The more the audience, the more would be the earning, which the nightingale was bound to pay to the frog as tuition fees. Moreover, he was happy that he succeeds in torturing the bird and pushing her towards death. However, it was bitter as he knew deep within his heart that the nightingale's talent surpassed his own and thus, nobody as great as the present audience had ever come to hear him from far and wide. It was pure jealousy.
