In order to take revenge on the scumbag, Song Nanzhi, who traveled back in time, mistook the current prince Mo Beihan for the princess's secret guard, knocked him out after sleeping, and sent him away. Mo Beihan deliberately requested an order to let Song Nanzhi enter the palace as a companion, and started an extreme tug-of-war with her, which led to constant misunderstandings. At the Queen Mother's birthday banquet, after Song Nanzhi performed a stunning dance, Mo Beihan appeared as the prince and fell off his horse. Song Nanzhi was stunned. On the eve of escaping from the palace, a marriage decree came and Song Nanzhi was forced to move into the East Palace.
