The Billionaire's Secret Daughter

Summary

After being reclaimed by my billionaire parents, I gained a naive and romantic younger sister.

She would show me photos of her fiancé and invite me to the mall to pick out a birthday gift for him.

She knew I used to be a photographer and begged me to be her wedding photographer.

She would also be distressed because her fiancé had a three-year-old daughter.

She thought of me again, hugging my arm and begging:

"Sister, you've given birth before, teach me how to get along with children."

But she led the child into the house, turned and went upstairs.
