The wedding preparation checklist shows that the bride and groom don't know each other is a female. Lin han, the servant of the duke, is the one who has prepared the wedding checklist for the bride. He tells the bride that she can't get married to Cai jin because she's a female, and that she should pretend to be male. He also tells the groom that he's been trying to be a brother to Cai for a long time, but that Cai is actually in love with her. He says that he was trained to be the emperor's secret guard when he was a young man, so he knows that Cai's feelings for her were misplaced. He asks the bride why she ran away while wearing the wedding dress, and she says that she was asked to do so by the duke. He then asks the groom if he can marry Cai, and the groom says yes.
