The three words that Gu Yusheng had said were thrown at her too suddenly, and Liang Doukou had no idea at first what he had asked. After swallowing the mango that was still in her mouth, she raised her head blankly and asked Gu Yusheng, "What?"
While giving her an unreadable expression, Gu Yusheng pursed his lips, and his voice was still very calm when he said again, "You know who I'm talking about."
Gu Yusheng paused, then repeated the words he had just said. "Where is she?"
It took about half a minute for Liang Doukou to realize that he must have been referring to Qin Zhi'ai, her substitute.
After she had come home, she had done nothing. In fact, she had only said a few words to him. How could he have found out that I wasn't her?
The smile on Liang Doukou's face became a bit stiff. She looked down and didn't reply to Gu Yusheng, but her brain was working at full speed.
