Only after her brother became prosperous would he become her reliable backer, allowing her to stand tall in the Ruan Family.
Yet, the Ruanlin Family had so much money and gave it all to Ruan Jianguo, which wasn't right. She should've spread the wealth among each son. Besides, before she came over, the Li Family had also mentioned that any mother would be heartbroken over her son's plight. It was unlikely that the Ruanlin Family could truly watch Ruan Jiandang struggle without money for his treatment. They were probably just putting on an act to frighten her.
Thinking about it, she felt it was indeed so.
As for Ruan Jiaojiao, she was even less worth mentioning. Such a money-losing girl would eventually benefit some other family. The Ruan Family's current doting on her was purely a lack of clarity in their thinking. They would eventually come to realize this.
So, she really didn't feel like she was at fault.
