Back at the palace, Cai tells roujia that she helped him out the other day, but that they don't really know each other as a princess. She's actually Cai's old friend, the daughter of the late emperor zhennan. She was brought up by the emperor and raised by him. Cai says that he grew up with her and the second prince, but the way he sees it, she only treats him like her brother. He's going to give her back his indenture, the one he signed when he first came to the palace. He tells her that he's found a maid named chunyan and that they're no longer in need of her. He also says that if she wants to leave, he can send someone over to bring her over. He says that chu yanche, the son of the duke , is the one who needs to be brought over to fetch her. Cai then says that she can leave anytime, as long as she doesn't have to stay in the palace for long. He adds that if he wants to find the duke, he'll send someone to fetch him. He then tells Cai to grab his sword and grab what's happening.
