Wen Erya's family came to the capital from Shuobei after her father was promoted. A wonderful match seemed to have fallen from the sky, but her father soon called off the engagement...
Ji Cheng is the heir to Prince Ning's estate. Born frail, he was told by the imperial physicians that he might not live past thirty. But his father doted on his concubines, and Ji Cheng's mother showered Ji De Yi, the son of a concubine, with affection. Though Ji Cheng was the legitimate heir, he had been expected to follow the rules since childhood and bear all the honors of Prince Ning's household.
A gentle, frail, and aloof man meets an innocent young woman. Is Heaven taking pity on him or teasing him by letting him encounter the last ray of sunshine in his life? Ji Cheng only wants to stay alive and grow old with Wen Erya. He doesn't know if such a wish can come true.
Though Ji De Yi is a son of a concubine, he enjoys the privileges of a legitimate heir. He was born on the same day as Ji Cheng, is the most handsome man in the capital, and is a notorious playboy. The emperor made an exception and granted him the title of prince. Everyone believes that when the heir to Prince Ning's estate passes away, Ji De Yi will be the next Prince Ning.
After marrying into the prince's household, Wen Erya seems to discover a secret: their horoscopes are incompatible, and if they become husband and wife, she is destined to bring her husband misfortune. Yet the Princess Consort of Ning insists they are a match made in Heaven and treats Wen Erya with great affection, though she seems to have some distance between herself and Ji Cheng and his mother.
