The world's first twin saints were born. However, while her older sister was gifted, the younger sister was an underachiever, a saint who couldn't even perform miracles. As they grew, the disparity in their powers only widened. Eventually, even those around them began to look down on the younger sister.

Despite being deemed incompetent, the younger sister, Astrea, still strove to be useful to others. However, she fell into despair upon discovering that even her earnest efforts were being usurped by her older sister, Hestia. It was then that Hestia commanded Astrea to attend an arranged marriage meeting in her stead, one that Hestia herself had no intention of going to.

Unable to refuse, Astrea traveled to a remote region for the arranged marriage. But who awaited her there was none other than Prince Silbart, the second prince of the neighboring country?

The Cinderella story of an unfortunate younger sister finding true happiness begins!
