Im probably wrong, but i think it is about a little girl and her father. the girl is born and the father does not know how to handle/help this girl grow up and raise her. he soon learns to play and have fun with her, they care for each other very much, until the daughter is ready to grow up, but is not ready for her father to leave, so when she leaves the cage (her childhood) she wants her father to come with her, but he cant as the girl must live life on her own and make her own choices,
