[The struggle for imperial power + the struggle of the queen's house + the charming heroine + the aloof prince + the young champion brother]
Because of being involved in the struggle for imperial power, the family was framed, the delicate heroine was assassinated continuously, and the family declined.
The aloof prince was the official who raided the heroine's house. The prince protected the heroine during the investigation, allowing the heroine and her brother to survive. And the prince also happens to be the one the heroine admires.
Forced by the authority of the royal family, in order to survive better, he could only seduce the aloof prince in all kinds of ways. Little did he know that the prince was also attracted to the charming heroine. He pretended to refuse while flirting, and he felt so happy in his heart.
After the people in the Hou family found out, they forced the heroine to enter the palace, and they almost killed the heroine several times. The prince protected his wife domineeringly, and only then did the people in the Hou family stop.
The heroine's younger brother was very good at studying, and later won the first prize in the imperial examination, which helped the family to overturn the case. Later, in order to help his sister, he fought with the prince in a battle of wits and courage, but was defeated by the prince's plan. In the end, the prince asked to marry the heroine.
