In the still of the night, the sound was abrupt yet distinct.
Du Yunluo was puzzled. Who would be knocking on the window in the middle of the night?
Although Princess Nanyan had mentioned that a message could come at the third or fourth hour of the night, the messenger would surely knock on the door, not the window.
However, since this was the Royal Palace, it was unlikely that any criminal would dare commit mischief in the dead of night.
Holding an oil lamp, Du Yunluo walked to the north window. Without opening it, she asked, "Who's outside?"
The lamplight cast a shadow on the window, and Du Yunluo heard the person outside chuckle softly and call, "Yunluo."
The familiar voice made Du Yunluo's hand tremble, nearly toppling the oil lamp.
She placed the lamp aside and pushed open the window, wanting to ask him if he knew what hour it was and what he meant by coming to knock on her window as a princely heir!
