If Shi Xiaoya was really the one who brought Luo Qingxian onto the set, that meant Shi Xiaoya had helped Luo Qingxian.
Was Luo Qingxian stupid?
If she helped her, why did she scold and slander Shi Xiaoya?
Luo Qingxian had been too loud earlier. And so, when she said that Shi Xiaoya was the one who helped her, no one believed her.
"You are shameless," Yan Zhiqing said. "You've just slandered Xiaoya. You did it boldly and loudly. And now, you are saying that Xiaoya was the one who brought you in here? If that were true, then you must be stupid!"
The idea to frame Shi Xiaoya came to her so suddenly that Luo Qingxian had forgotten that she had yelled at Shi Xiaoya earlier.
While she was trying to save herself from this situation, she heard Wei Wucai say, "Actually, there's an easy way to solve this issue. We just need to check the surveillance cameras at the door."
