When the emperor's mother comes to visit the emperor, she asks the son why he has time to visit her. The son says that his mother is confused and has mistaken him for his brother. The mother tells the son to take a walk in the imperial garden if the emperor comes. She also tells him to tell the empress that he has been mistaken for the emperor before. The empress tells him that he is the late emperor and that she mistook him for the current emperor. The emperor is shocked at the news. He asks the mother to explain that after the emperor succeeds in marrying his sister-in-law, his family will be released from the palace and will be reunited with him.
