One day, when the young ladies were of age to be married, a terrible, three-headed dragon laid siege to the kingdom, burning villages with fiery breath. It spoiled crops and burned churches. It killed babies, old people, and everyone in between.
The king promised a princess’s hand in marriage to whoever slayed the dragon. Heroes and warriors came in suits of armor, riding brave horses and bearing swords and arrows.
The king sent his three daughters one by one to fight the dragon but he debuted them, the king was left aching with grief and now he was alone, only with your partner.
I think the message and purpose that the author wants to give is that a pretty face and kindness are not a means to discuss something so strong and if you fail once, don't risk more.
