A beautiful medical girl traveled to a bloody battlefield. She became his prisoner. She performed operations to treat soldiers, but was regarded as a forbidden concubine by him. With an imperial decree, she became his humble maid. She was forced to sleep with him on the first day, and was framed by his concubines. There is a rumor in the harem that she is a monster, just because she saved his first prince by caesarean section and gave him the title of noble concubine. He is the most ruthless and cruel king of the five kingdoms. He has never been emotional for a woman, so she made an agreement with him. A piece of paper that exempts her from guilt hides a mystery. In the red gauze tent, he took her first night away from her. She was just one of his countless women, whose dignity was trampled under his feet... I thought that giving her true love would win him back, but because his wife arranged an operation that was destined to fail, she became a sinner, the monster appeared, the country was destined to perish, and she was going to be pushed to the stake...
