What Game Is She Playing?

"Are you sure that you don't understand what I mean or do you just don't want to understand?" Do you really think that Jiang Cheng will be able to do anything for her? Even his older brother Jiang Changdai, who is the president of the Jiang Group won't be able to affect Director Kang's decision. Who do you really think you are? Do you think that you and those dumb friends of yours are so important that everyone will start to listen to you? What is your brain made of?! 

"I didn't do anything. I didn't!" Lu Beichen was shocked. He was suprised that Lu Sichen actually knew of this. He made sure to tell Jiang Cheng not to tell anyone else about this. How did Lu Sichen find out about it?
