Han Manyin could tell that Pei Yansi was using her to assert his authority.
However, she wasn't interested in Pei Yansi at the moment, first because she knew she couldn't have him, and second because she knew how ruthless Pei Yansi could be. Provoking him was more than she could handle.
Thus, she felt neither jealousy nor anything else regarding Pei Yansi's display of power.
She deliberately continued the conversation, "So, you two are married, no wonder you look so good together. Heyu, I've heard President Shen mention you before. I'm so glad to finally meet you today, I truly envy you."
A trace of innocence emerged in Han Manyin's eyes, her bright eyes looking at Shen Heyu as if she were naive.
People who have experienced amnesia tend to forget their grudges, and she was now pretending to "not remember." Since she didn't remember, she treated Shen Heyu without hostility, and thus her gaze was pure.
