The heroine: Shen Zhaozhao, who appears to be a "sick concubine" raised by the Shen Mansion in the capital, but is actually the daughter of the eldest princess who has been missing for many years. She has been raised under the protection of a hidden identity since she was a child. She is proficient in the art of treating poisons (she was taught by the hidden miracle doctor), and her soft-tempered appearance hides a poisonous tongue and intelligence.
Male protagonist: Pei Jue, the regent, a powerful, cold-faced and dark-hearted God of War. Shen Zhaozhao inadvertently saved her life when she was young. He believed that she was his "little benefactor" and guarded her secretly for many years, but he always found the wrong person.
