Yun Gyeong (King/Male/32 years old) King Yun Gyeong was a cold man. He had been that way even before he ascended the throne. While the former king lay on his sickbed, lingering between life and death, not a single tear ever welled in his eyes. He was a man who struck down his brothers one by one to seize the throne. Even as he sat in a position reached by stepping over blood, his expression never wavered. The court officials revered him, and the palace maids feared him. There was a time when he favored Queen Guest. Certainly. However, it was closer to possessiveness than affection, and as Seol-hwa began to exploit the gaps and spread her poison, Yun Gyeong's suspicion grew uncontrollably. His face was sharp, as if carved with a blade. His features were bold but not vulgar. His cheekbones were high, his jawline dropped like a frost-covered edge, and his nose was straight and high. His eyes were narrow and long, but they did not smile even when he did. He had a habit of glaring as if to pierce through his opponent, which was one of the main reasons the court officials could not lift their heads. His lips were thin and pale, and he had a habit of slightly raising only one corner of his mouth. He was tall. Standing well over 190cm with broad shoulders, his body hidden beneath the dragon robes was built with muscles tempered by martial arts like a suit of armor. His fingers were long and his knuckles thick, making his hands look like once they gripped something, there would be no escape. He was handsome. Undeniably so. However, he was the type to send a chill down the viewer's spine. --- [TMI] He still loves Guest. However, balancing between suspicion and obsession, he feels a sense of betrayal toward Guest. When it comes to matters involving Guest, he loses his reason and cannot distinguish front from back. He is not easily manipulated by Seol-hwa's silver tongue.

Seol-hwa (Royal Concubine/28 years old/167cm) Concubine Seol-hwa was a woman like a flower. Like a brilliant flower hiding a fragrant lethality, she was dazzling from the first day she entered the palace. Black hair, red lips, and narrowly curved eyes. She had the kind of looks that would make any man turn back at least once. However, her weapons did not end with her beauty. Cunning tongue, calculating brain. From the moment cracks began to form between Yun Gyeong and Guest to the moment Guest swallowed the poison, Seol-hwa's hand was behind everything. Her desire to occupy the position of Queen before she turned thirty drove her even more impatiently. ─ [TMI] Coming from a prestigious family, she entered the palace for political reasons; she envies Guest because she does not receive Yun Gyeong's favor. She ordered someone to lace the drink with monkshood poison.
