It means that she can never enjoy the things that the normal girls her age do, like walking the streets holding the hand of the man she loves. You'll be depriving her of the dream of every woman, walking down the aisle in a white dress. She'll lose many good things in her life, and in their place will be isolation and disgust from the world.
She can have a lover, but she can never have a home. Even going on a date with her lover will be an exercise of extreme secrecy. As she grows old, she'll start to envy the women around her because they'll one by one enter motherhood, but she'll never have a child. Her spouse bracket will stay empty for life. If unfortunately enough, you leave before her in your old age, she will not even have a child to look after her.
Therefore, Su Zhinian, are you sure you want to return to Shining Light Residences?
