Shen Gu noticed Hua Feifei's current attitude was surprisingly good, not at all like someone who was upset or angry because of Wu Jiayi's "public confession" to him.

This was quite different from how she had behaved in the waiting area earlier, almost like a different person.

So, he surmised that Hua Feifei might have already figured out how to handle this "public confession" incident. The reason she called him alone was likely because the "solution" was closely related to him and required a private discussion.

However, Shen Gu didn't want to be the one to ask about the solution.
