For Doctor Qin, knowing the truth was actually less desirable than remaining ignorant.
From the perspective of moralism, she felt she should tell Gu's mother about the matter. However, as a psychologist, she couldn't do that. She had an obligation to keep all patient information confidential. He Zhilan was aware that Gu's mother was her biological mother, yet harbored hatred in her heart, unwilling to speak or recognize her. Therefore, if she were to tell Gu's mother about He Zhilan being the lost daughter, Gu Zhilan, without He Zhilan's consent, it would be unfair and intrusive to He Zhilan.
Yet, Doctor Qin really wanted to help He Zhilan, and she wanted to bridge the rift between He Zhilan and her biological parents.
"By the way, do you know if there were other conflicts between He Zhilan and the Gu Family in the early days?" Doctor Qin thought her friend might know something, having once been close with the Gu Family.
