The only person Ming Ge could think of in this Duke Manor, related to her, was one person—
Madam Olya.
Concerning someone who might be her mother, Ming Ge had to be cautious, careful, and prudent.
So, she tested Yu Ruoxun a bit.
Sure enough.
After hearing her say that she felt Madam Olya looked a lot like her deceased mother, Yu Ruoxun's expression changed.
Despite her efforts to hide it, she couldn't fool someone who was keen on observing her.
Hence, Ming Ge could finally confirm that Madam Olya was very likely the one who died in a plane crash, but for some reason survived, and became the mother of Duke Charlie's soon-to-be bride, Yu Xinying!
Yu Xinying... Yu Ruoxun... both have the surname Yu...
Yu Ruoxun said that Madam Olya was her godmother, so Ming Ge had reason to suspect that Yu Ruoxun knew the truth.
Knew Madam Olya's true identity.
This knowledge, fortunately, wasn't too late.
