The path for Colleen to become the Southern Queen was filled with thorns and stones. It wasn't like in the fairy tales where the beautiful common girl gets married to the prince and they live happily ever after. However, the common folks, especially the citizens of the Southern region believed her life to be a real-life fairy tale.
Though the Southern Ruler's family might have accepted Colleen for the sake of the Southern Ruler the rest of the royal society and high society did not. They did not let go of any opportunity to mock and ridicule Colleen. They took every chance they got to remind Colleen that she did not belong among them. With Colleen being an ignorant commoner and straightforward soldier they never lacked the opportunity they sought.
