At the banquet to break off their engagement, she brings out a box of perfume ledgers. Xie An, the third young master of the Duke of Xue's household, is mocked by everyone as a spoiled playboy who is burdened with gambling debts. Princess Li Zhaoning initially intends to break off her engagement with him. Little does anyone know that Xie An is actually Su San, the alias of the owner of the Su Ji Perfume Shop in the city. Duke Xue impeaches him at court, accusing him of misleading the people and disrupting public order. Xie An immediately produces his account books, revealing proof that the Xue household ordered hundreds of bottles of perfume. The accounts are crystal clear. This seemingly ordinary broken-engagement dispute, accompanied by a box of perfume ledgers, triggers an astonishing reversal.
