He Zhilan didn't explain to He Dongxue. He Dongxue isn't her and naturally wouldn't understand how much she missed her birth parents. She was the only child of her parents. Without her, they must be heartbroken.
However, she also knew that if she left the He Family for the sake of finding her biological parents, she would be too conscienceless.
He Dongxue was caught in a difficult predicament. She was extremely curious about what had happened before He Zhilan was kidnapped, in particular about her birth parents. Especially after finding out that He Zhilan's father was also a military man, her curiosity was piqued. But, on the other hand, she was irritated when He Zhilan mentioned her birth parents and looked sad. It seemed to He Dongxue that He Zhilan was a little callous.
This conversation spoiled He Dongxue's mood to be tutored by He Zhilan. Picking up her homework, she rose and left the room.
