Ever since being threatened by Ling Ruonan the last time, Ouyang Huihui had been very concerned about Luo Ziling's safety.
She was truly afraid something unexpected would happen to Luo Ziling, and that Ling Ruonan would blame her and her sister for it.
Ouyang Huihui also feared Ling Ruonan might mistake the incident as her plot and direct her anger towards her.
Therefore, when she saw the message in Luo Ziling's circle of friends, she immediately became incredibly anxious.
It wasn't Cao Jianhui who had called him for help; although Luo Ziling knew her phone number, others did not.
It was she who took the initiative to call Cao Jianhui, only then learning the full extent of the situation.
Before calling Cao Jianhui, she had tried calling Luo Ziling, but he hadn't picked up.
After getting the details, she immediately sought help from her sister, Ouyang Feifei, and prepared to head to the Huding Police Station right after the call.
