Gu Yifeng never expected that Mrs. Dong had such a relationship with Prince Xian, and even the Holy Emperor knew about it.
After returning to the East Mansion, Gu Yifeng re-interrogated Mrs. Kong, and Mrs. Kong revealed what she had overheard. It was then that Gu Yifeng learned that before Mrs. Dong married into the Marquis Mansion, she had already been secretly involved with Prince Xian.
She even knew that Mrs. Dong had lost a child for Prince Xian, which explained why over the years after marrying into the Marquis Mansion, she only gave birth to Sister Hui and had no other offspring. It turns out it was because she had hurt herself back then.
Thinking about how over the years, because he was with Sister Ning, Gu Yifeng felt especially guilty watching Mrs. Dong live well. Even if Sister Ning didn't say anything, Gu Yifeng understood in his heart.
