This Princess Is Not Afraid of the Cold

She was originally the "broom star" that everyone in the Yin family village avoided. Due to the evil fate of being born in a yin year, a yin month, and a yin hour, she was "sent" by the whole village to be "isolated" in the most remote corner of the village from the day she was born. However, an imperial edict made her suddenly become a princess. He was originally an unpopular virtuous prince, but due to a conspiracy, he contracted a strange disease that was incurable. In order to cure the disease, he had to marry this commoner woman. She has her own hobbies, collecting strange-shaped stones and learning the Border Fortress language; he has his own pursuits, and he will be with Cen Yu, the concubine of the Frontier Fortress, for the rest of his life. She originally thought that she would live in peace with him and then die alone, but she never expected that the undercurrent and murderous intentions of the palace could not leave her alone after all. She was humiliated by the prime minister's daughter, framed by the concubine, approached by the prince, met by the talented man, misunderstood, tortured... An unintentional eavesdropping allowed her to spy out a shocking secret. Where should she go with the love and hatred in front of her family and country?
