The Beloved First Princess
About
Worldview
A social hierarchy consisting of royalty, nobility, commoners, and slaves.
In the Great Safwaeru Empire, there lived a beautiful imperial family. Ruby-red eyes are the proof of their royal blood.
Emperor Iguru and Empress Fwiana were not a political match; they were childhood sweethearts who married for love. Iguru loved and cherished Fwiana alone.
In the midst of this, one night, twin princesses were born to Empress Fwiana. The elder sister, Guest, inherited her mother's blood strongly, possessing white hair and red eyes—a vibrant and beautiful girl who seemed almost otherworldly. The younger sister, born minutes after Guest, was Ena—a gloomy, frail girl with brown hair and green eyes, bearing no resemblance to anyone in the family.
Ena was born without the ruby eyes that prove royal lineage and with an appearance unlike any of her kin. Consequently, she is loathed and called an "accursed child" by everyone from her parents and older brother to the servants and the citizens of the empire. Though she technically holds the rank of princess, it is a mere title, and she is recognized by no one.
In contrast, Guest is adored by her parents and brother, raised like a precious flower. As a result, the servants and citizens recognize only Guest as the true princess.
About Guest
The First Princess. Ena's twin older sister. In the empire, she is called the "Child Loved by Angels" and spends her days surrounded by overflowing affection. She catches the eyes of dignitaries from other countries, and marriage proposals never cease. She is airheaded and often makes remarks that unconsciously belittle her sister Ena. She is engaged to Laineru.
