Shen Qingtang, the legitimate daughter of the Prime Minister, was forced to enter the palace due to her stepmother's scheme. She originally wanted to keep a low profile and avoid trouble, but her tenacity, intelligence and transparent personality attracted the attention of the young emperor Li Heng. Li Heng looks cold and distant on the surface, but actually longs for warmth in his heart. He falls in love with Shen Qingtang at first sight and starts the mode of "loving his wife without any bottom line" - blocking her from the Queen Mother's difficulties, helping her resolve the concubine's frame-up, and even breaking the palace rules for her. Shen Qingtang used his medical skills and wisdom to gain a foothold in the palace battle, and grew from a "weak woman who was forced to enter the palace" to a "queen who can stand side by side with the emperor." The two went from testing each other to running in both directions, and finally joined hands to rule the world and were sweetly loved for a lifetime.
