Director Zhang had already decided that he wouldn't show any favors or partialness to his niece.
Yet, because of Xu Lei's sudden appearance at the audition, he just broke one of the principles he established upon himself.
But now, even his niece, made him lose face!
The crew saw that Director Zhao was having trouble with his niece, the supposed second female lead in the movie, and they couldn't help but look at the closed doors of the filming studio where the rest of the actors and actresses were waiting.
Deep inside, they already knew that Director Zhao just had lost some points in the duel for the second female lead role.
Great answer!
