Lin Yue, a modern history buff, is unexpectedly transported back to the Kangxi era and becomes the principal wife of the Fourth Prince, Yinzhen. The moment she opens her eyes, she faces the strict rules of an ancient prince's manor. She gets the formal greeting wrong, fumbles the dining etiquette, and lands in one awkward situation after another, nearly humiliating herself beyond recovery. But with her modern knowledge, she quickly establishes herself in the household, even teaching the maids to make mops and mix cocktails, leaving everyone amazed.
Beneath the surface, the struggle for the throne is brewing, and the various factions are poised for conflict. Lin Yue grows close to the cold-faced Fourth Prince, facing one crisis after another by his side. At the same time, she uses her modern wit to navigate the palace and the prince's manor, deftly unraveling plot after plot. She matches wits with the palace consorts and wins support for the Fourth Prince. At court, she helps him tackle one challenge after another, setting him apart on the road to the throne.
In the end, the Fourth Prince ascends the throne, and Lin Yue naturally becomes empress. As the mother of the realm, she reforms the inner palace, hosts cultural exchange events, and supports charitable causes, winning the respect and affection of the people. And through all the twists and turns of those years, her love story with the Yongzheng Emperor becomes a timeless legend.
