Previously, Yu Heng did not know that Yu Wan had been specially trained and groomed by her own mother to make her behavior and attire resemble Yu Yao's, then deliberately sent to the Yu family.
It seemed that before Yu Wan's mother met Yu Hong at the orphanage, she had already made plans to send her biological daughter to the Yu family. However, they did not know how long she had been planning this for.
Thinking of this, he looked at Yu Wan solemnly and asked, "Yu Wan, did your mother design for you to be adopted by the Yu family only after she found you, or after Yaoyao disappeared, or was it before she even came to work in the Yu family?"
The difference in timing determined whether Yu Wan's biological mother committed the crime. If she had only decided to send Yu Wan to the Yu family to become their adopted daughter after Yu Yao disappeared, then it could only be said that she was a smart woman who wanted to use her biological daughter to gain benefits.
