No, You Must Be Mistaken

  "Go. Just say that my clothes are dirty. Ask them to go back to the palace and bring a set of clean clothes for me." After arriving at the washroom, Su Ying gave her instructions to Lin Zhu.

 Lin Zhuyu asked, puzzled, "Does Your Imperial Highness have some sort of plan?"

 Su Ying glanced at her indifferently. "I have to verify something. I will go out in a while. Think of a way to stall for time."

 Lin Zhuyu didn't ask any more questions. Her face was solemn. "Don't worry, Your Imperial Highness. I will not disappoint you!"

 With that, she turned around and left the washroom. A moment later, Su Ying heard her slightly arrogant voice from outside the door. "Some water accidentally splashed on Her Imperial Highness's dress. You gals must immediately return to the palace and bring a set of clean clothes for Her Imperial Highness."

 After the door to the inner hall was closed, Su Ying jumped out of the back window.
