It was not that Yan Qingsi did not want to protect Tang Yuyao, it was just that Yan Qingsi did not have enough influence to protect her. Seeing Tang Yuyao get dragged in the mud like that while she remained helpless on the sidelines. She got her into this mess, but she could not get her out of it.
With Yue Tingfeng's help, Yan Qingsi could finally heave a sigh of relief. At the very least, she was able to give Tang Yuyao a proper escape from this mess.
Yan Qingsi's gratitude was heartfelt at that time. It was not sarcasm and it was not a joke. It was real.
Yue Tingfeng was the first person who was willing to reach out and lend a helping hand. Even if they went their separate ways in the future, it was a favor she would never forget.
