I am not sure what FL will do, but I am all for her leaving the man with a letter about Separation, because Zong Yue (ML, Wei Wang) is still being a shitty man, despite he does care about her and tries to appreciate her value. Not sure if he's pretending or what, but what everybody knows is that he is pampering this new woman, and the woman herself tries to intercept Feng Sheng when she's going back home to introduce herself as a Concubine, but Zhiqiu (her other maid) cuts her out and tells her she hasn't been recognized (no tea ceremony has been done) by the wife. Regardless of Feng Sheng (FL) being smart and knowing there's someone's work behind it, he still hurts her by bringing a woman from his first wife's family (Qing) into the house. What I want to say here is that the ML is still an idiot in this part.
It is all a scheme from one of her maids, Zhichun, which I'll develop further later.

Zong Yue knows that he could marry Fang Feng Sheng because he had blocked all her paths of retreat. But walking down this path, she discovered that there were things beyond her imagination. Her father was implicated and put to death, and she paved her way through thorns to prove her name. She was the only descendant of the Fang family, the most prominent family of private advisors in Shaoxing. There’s a famous saying in officialdom: there’s nothing to lose. “When everyone scorned me because I was merely a woman, I kept convincing myself: ‘Actually, you can give it a try.’” – Fang Feng Sheng
