Temirana: The Lucky Princess and the Tragic Knights

This is a world in which status and occupation are all determined by the month of birth. At the eastern end of the country of Temirana, about fifteen years ago, a baby with a bruise on her forehead was born as the third princess. The baby was rumored to be a "cursed princess" and was forced to live separately from her family in a mansion away from the castle, but a big turning point came for her.
