Raon disguises herself as a man named Samnom and does all kinds of work to earn money, pay off the debts and find her mother. One day, she is kidnapped by the moneylenders, and they sell her to the Office of Eunuch Attendants to get their money back.

The King personally orders Raon to deliver his response of Consort Park's letter, and it turns out to be a secret letter written with apple vinegar.
