This was something that indeed touched Ling Chuxia's heart.
When she was pregnant with her first child, she thought, even if the child couldn't grow up beside his father, she would do everything she could to give him the best. She would personally design the house for him, buy lots and lots of toys, and make sure he grew up happy and joyful. But sadly, that child... left her.
All her plans for the child could not be realized, which was truly a regrettable matter. Now, Shi Che's proposal immediately rekindled her memories of that child.
But that child is gone now and can no longer return. What she has is the child she has now.
Yet, she still feels some trepidation with this child, so she's somewhat hesitant to invest her emotions, instinctively holding back from doing anything for him.
