Hi! I came across a novel wherein a general's daughter and her brother were traveling to return to the capital. On the way, they needed to stop by an inn where an official who wanted to get her father (the general) impeached, was imprisoned. The daughter who was pretending to be sick engaged in verbal sparring with an official. There were also spies in the inn who wanted to assassinate the official and point the blame towards the general. However, they did not succeed as the general's daughter prohibited the official from eating meat (she did not know it was poisoned). She saved the offical's way by accident so the official changed his mind and began to admire the general's family. When they arrived at the capital, the general's daughter continued to act very sickly. Her brother supported her and their interactions or banter were often hilarious.
