When Tan Rou and the others were talking, they didn't deliberately go behind others 'backs, so they didn't notice someone secretly following behind them.
Chen Yao heard Tan Rou's conversation and was very afraid. If Lan Ning sued everyone, would she be sued by Lan Ning, too? She couldn't afford to pay that much and didn't want to go to jail.
Moreover, from what Tan Rou and the others said, they had already treated Lan Ning as a good friend. Since they had chosen Lan Ning, she did not need to be friends with them.
Originally, Chen Yao was very envious of Tan Rou and the others. Not only were these people very close, but they also came from rich families, especially Tan Rou. It was said that she was the eldest daughter of the Tao family in the capital, and her family had endless money to spend. Chen Yao wanted to build a good relationship with them, but unfortunately, they supported Lan Ning in fighting the lawsuit, so there was no need to please them.
