The day after Xiao Jingyuan, the new emperor of the fictional dynasty, ascended the throne, the former empress Su Qingqing left a note "You are a wise king, and I am a common concubine. It is better to forget each other." She took away half a box of gold and silver and left the palace. Before Xiao Jinyuan could digest the absurdity of "being divorced", the Queen Mother and the court officials brought in dozens of concubines on the pretext of "filling the harem and stabilizing the country." But when he took a closer look, he found that the harem had become a "gathering place around the former queen" - Concubine Shu was the former queen's best friend and "supervised" his meals every day; There were senior ministers in the court urging the queen to be appointed, and there were concubines in the harem helping the former queen "fight for her favor." Xiao Jinyuan repeatedly jumped between "handling government affairs" and "explaining that he had not forgotten the former queen" every day. What makes him even more troubled is that from the occasional news from the public, the former queen seems to be secretly "paying attention" to his harem, and behind the seemingly funny daily life of the concubines, there seems to be a struggle between the court forces hidden behind it. He is more tired as the emperor than when he was the prince - after all, the prince only needs to study, and now he has to guard against being "brainwashed" by the concubine while looking for opportunities to find out why the former queen left and what she was "planning".
