This story is about an old couple who had no children, and just as they were in deep despair, a frog was born from the old woman's knee. Moreover, the frog told the old couple that, when he grew up, he would marry the king's daughter. The couple failed to stop their frog-son from going to propose the princess. And, using all his skills, the frog succeeded in marrying the king's youngest daughter. At the wedding, the king's two older princesses saw a prince in white riding a white horse, who was in fact the frog prince. One day, the youngest princess secretly burned the frog’s shed skin, so the frog prince left the princess.
