She had investigated Lu Yu's background and found that he had many girlfriends. Although she looked cold on the surface, he was actually a very lecherous person on the inside.
When Mu Chen had sent the message, she had happened to be discussing business with Shi Mo. How could she miss such a good opportunity? Hence, she had taken the initiative to request that they discuss their business another time and go to the film set to take a look first.
She said that she had something to discuss with the director as well.
Hence, the two of them had stopped what they were doing and come over to look for Fang Mo'er.
She already knew where Fang Mo'er was, but in order not to expose herself, she pretended not to know and went to the hotel with Shi Mo. Fang Mo'er was not there.
She then pretended to ask the staff first, so that the two of them could arrive at the night market just in time.
