bear and piano

One day, in the forest, Bear saw something he had never seen before, and it was a piano.

He tapped with his chubby little paw, and from then on, there was the sound of the piano in the forest. Day after day in spring, summer, autumn and winter, the little bear went to play the piano every day, and gradually, the little bear grew into a big bear, and he played to his heart's content every day surrounded by his friends. Until one day, a father and daughter who passed by the forest told him that the outside world was wonderful, so he followed them out of the forest and went to the bustling city full of longing. He performed in splendid theaters and became a highly anticipated pianist. However, in the bottom of Big Bear's heart, there is something vaguely worried about him.

Finally, the big bear decided to return to the forest, what will be waiting for him?
