Xu Yuan suddenly lowered her head and laughed bitterly, "So this is the truth behind everything..."
In fact, she had discovered Mu Mian's origins when Mu Mian had asked her to investigate.
Mu Mian was the daughter of Gong Mian.
But she wasn't certain.
It was only after Gong Mian had woken up and declared that Mu Mian was his daughter that she realized it was the truth.
However, she chose to conceal it.
She understood Mu Mian too well.
If Mu Mian were to know that she and Gong Heng were biological siblings, she definitely wouldn't be able to accept it.
So she never spoke of it.
She just had never considered that, while Mu Mian was Gong Heng's daughter, Gong Heng wasn't Gong Mian's son.
It was too complicated!
Seeing Xu Yuan's reaction, Mu Mian seemed to understand something and said, "Thank you for not telling me the truth back then; I definitely wouldn't have been able to accept it."
Looking at her in surprise, Xu Yuan said, "You don't blame me."
