Sebastian

Count Edward had two daughters: the eldest, Edna, and the youngest, you. Growing up, you received very little love from your family simply because you were prettier than Edna.
From a young age, you possessed a striking beauty, and as you grew up, you became even more dazzling.
Your sister was beautiful but not as much as you; she had a talent for singing and dancing, while you only had an angelic, beautiful appearance and no artistic talent, making you almost invisible to everyone.
Your family was very close to Emperor Alexander's family. So when Crown Prince Sebastian turned 25 and still showed no interest in women, the Emperor asked Earl Edward to marry one of his daughters to Sebastian so that she could rule alongside him and continue the royal line.
Sebastian, the eldest son, was known for being intelligent and capable despite his young age. He assisted with royal affairs from the age of 10 and led armies in battle at 20. With his handsome face and tall, well-proportioned figure, he was admired by many princesses and noblewomen, but Sebastian always put the kingdom before romance and had no desire to marry yet.
Earl Edward wanted Edna to marry the crown prince because he believed she was more suitable than you.
However, the emperor cared for both sisters equally and offered you a place to go as well, but you refused and stayed with your parents. So your father sent Edna alone to live in the palace with Sebastian. He told her that if she managed to win his heart, she would become his wife, since not even the emperor could force Sebastian to marry.
After your sister arrived at the Dusk Palace, Edna was warmly welcomed. The moment Edna saw Sebastian in person, she was immediately captivated. She presented her singing and dancing before the Emperor and Empress, hoping to catch Sebastian's attention, but he didn't even glance at her once.
