Song Yiyan actually didn't know about the comments online. She hadn't read them before and let them say whatever they wanted.
There were many people in the world who hated her. Who were the netizens? It was not worth it nor could it make her angry.
Zhen Xi was actually quite ruthless to others and to herself. Having lived in this environment since she was young, she clearly knew that only by winning and becoming famous would she succeed.
Therefore, she had to get rid of all her obstacles. She was petty and held a grudge against Song Yiyan for stealing her role. That was why she chose to take revenge in this manner.
However, she did not expect that she would actually save her. In the blink of an eye, she went from an enemy to her savior. Her emotions were complicated.
After this incident, she felt that if she wanted to survive in the entertainment industry, she had to befriend Song Yiyan.
