"What's wrong, Li?"
Sheila asked with some curiosity.
Li Ang made a quieting gesture, slightly lifted his neck, and carefully confirmed again before he heard the sound of a window being moved, which then completely disappeared.
Li Ang wanted to tell himself it was just the wind moving the window, but he knew all the windows in Sheila's home were sliding windows, which could not possibly be blown open by the wind.
"It seems like a window at the back of your house was pushed open."
"Yes, I'm not sure, but I also thought I heard a sound just now."
Sheila's voice trembled slightly, for she could be a dazzling beauty or a mature professional, adept at mingling with various social circles.
But in this situation, as a woman living alone, she inevitably felt afraid.
"Are your back windows locked?"
"Maybe, I think I opened them for ventilation this afternoon, I don't know, oh my goodness, what should we do?"
