Madame Min was still alive, and she did not have to be worried, because Madame Min was someone who stuck to the rules. Her son was definitely going to inherit the family affairs. So she was very assured while Madame Min was alive.
First Ms. Min was different from the madames from other mansions. She never hoped that Madame Min would pass away as soon as possible so that she could take over the mansion completely. What she knew was that when Madame Min passed away, she would not be able to suppress the issues. While Madame Min was around, everything would be well. She had no idea what her whole life would be like afterwards.
That was what she was worried about the most when Madame Min got sick the day before.
