Back at the Mu family, Matriarch Mu had used the excuse that Xue Yun could not give birth to a son to torture her mentally. At that time, she had tortured her until she became depressed. Naturally, this birth of a son had left a deep impression in her heart.
This made her want to give birth to a son even after she lost her memory. She felt that once she had a son, she would have everything and wouldn't have to suffer anymore.
This subconscious belief made Ling Xiao, her son, especially important to her.
Furthermore, for the past eight years, Ling Xiao was the only child in her world. Hence, her bias was instinctive.
Instinctively, she would not feel that she was biased. No matter how much she did, she would not feel that she was going overboard. In fact, she would even feel that Mu Huan was wrong. Not good. Ling Xiao was her younger brother! Her biological younger brother! No matter what, she could not ignore him! She could not watch him lose everything!
