Just friends?
If they were really just friends, why was Mu Baicheng so anxious when he received Ah Xiang's phone call?
At this point, Old Lady Mu patted Zheng Niannian's hand, "Niannian, although Chengcheng hasn't shown any clear feelings for you yet, believe me, he definitely has you in his heart, he's just not good at expressing himself. Moreover, I have already set my mind on you as my daughter-in-law. Besides you, I don't want anyone else."
After speaking, Old Lady Mu continued, "Chengcheng's biggest flaw is that he's too softhearted. That woman named Ah Xiang must have run into some trouble, so he hurried over. Niannian, don't be anxious, and don't be angry. Once you and Chengcheng have established your relationship, you can talk to him properly about this matter and ask him to keep his distance from those irrelevant people. I can't guarantee anything else, but I'm sure there is nothing wrong with Chengcheng's character."
