Mu Shuoqian was handling official business in his study, with the keyboard clattering loudly. Behind him, the black and white floor-length curtains tightly blocked the moonlight from the windows.
A faint knock on the door reached his ears, soft as if a small cat was scratching at the door.
He slightly furrowed his brows, glancing briefly before continuing with his work.
"Come in."
After about half a minute of pause, there was no movement outside the door, nor did anyone push it open. It was only him and Gu Qili at home; who else could have been knocking if not her?
He ignored it, continuing to type on his keyboard.
Some time later, the knocking sound resumed, slightly stronger this time as if worried he hadn't heard, like a small dog lifting its paws scratching at the door.
"Come in."
Still, no one entered, and the doorway remained silent.
