As the victim of the case, when Shan Jiaying woke up at the hospital, obviously there would be police debriefing her, but due to the immense backstory, the police officer obviously could not tell her entire story. Just like at the Grand Piano Competition, Li Dan’s name had not been mentioned to her.
But when Zhao Yu mentioned Li Dan’s name, Shan Jiaying was not surprised or even hesitant, as if she recognized that name. Not only did she know Li Dan, but she even knew ahead of time that the person who attacked her was Li Dan! Additionally, Zhao Yu had not even mentioned what had happened, but Shan Jiaying knew exactly what had happened to Li Dan, making her even more suspicious. As it turned out, Zhao Yu had already set up the trap, waiting for Shan Jiaying to walk into it.
Shan Jiaying also realized she had made a mistake, and sat there squirming, and picking at her arm.
