When Ah Chen first heard from Bai Huimei about how Xu Chang and Lu Mingxue went from having a mediocre relationship to being inseparable, and then suddenly divorced, she began to speculate about Xu Chang's situation.
Now, after inquiring from Ji Wuyan, she found out that Xu Chang had experienced amnesia before, which more or less confirmed what could have happened to her. Most likely, it was similar to what the Commissioner went through—was it done by other members of the Nightingale Clan?
This also explains why Lu Mingxue reacted so indifferently upon learning that his eldest son's body had been possessed by someone else.
It's not that he doesn't care for his eldest son; rather, he knows Bai Ying will eventually leave Lu Fengqiu, and he somewhat embraces everything about her, thinking Bai Ying is of the same kind as the one who once inhabited Xu Chang's body.
It's truly…ironic.
