Ye Wanwan was originally immersed in the study of alchemy in her alchemy room. However, upon hearing that Ye An'an had arrived looking for her mother, she couldn't contain her curiosity and lost interest in her research. Consequently, she hastily made her way, coincidentally meeting her mother halfway.
Lian Mengzhu was somewhat surprised by Ye Wanwan's sudden appearance because Ye Wanwan had complained extensively about Ye An'an the previous night.
Clearly, Ye Wanwan harbored deep prejudices against Ye An'an. Consequently, she didn't anticipate Ye Wanwan joining the gathering. Nonetheless, from her perspective, it was a positive development. Ye Wanwan was no longer young, and as the future bearer of the Ye family's responsibilities, she couldn't afford to act recklessly.
Now that Ye Wanwan was willing to set aside her grievances and exhibit the demeanor of a host, it signaled a level of maturity.
