She knew Sun Ruoruo's existence. Ming Suyang talked about Sun Ruoruo before. She thought it was just a childhood friend. She did not expect turned out it was different to Ming Suyang.
Before Bai Feng Jiu met Ming Suyang at the mall, she witnessed Ming Suyang kiss Sun Ruoruo. She was furious. However, she was not an idiot to go and confront these cheating bastards and bitch.
She had another thing to do. She never expected that Sun Ruoruo would frame her for something that she never did. It was the feeling of how being targeted by a white lotus bitch. She just found out. Well, she could not dare to say it was a good feeling.
