Yu Xiaohui's guess was completely correct.
Because after Wu Mengting became Chen Feng's girlfriend, she immediately sought her out and tried to persuade her to back off. This undoubtedly dealt a huge blow to her self-esteem, and it could even be said it was a humiliation.
Then she directly used a commanding tone, telling Sun Xiaorui to sleep in separate rooms from Chen Feng.
This undoubtedly further provoked Sun Xiaorui, and it could even be said it angered her.
From the moment they met, Sun Xiaorui had always been humble and respectful in front of Wu Mengting, looking up to her and giving her the utmost respect and courtesy.
The result was that Wu Mengting hadn't even officially taken her position, yet she immediately tried to persuade her to retreat, which naturally made her feel uncomfortable, even feeling a sense of betrayal and deceit by Wu Mengting.
Of course, the real reason that prompted Sun Xiaorui to ally with them was the sense of crisis in her heart.
