"Those labs are under Lin Family, so there's conflicts between Father and Mother, right?" Nan Xian Yu asked.
He had been meaning to ask this for a long time because he could remember that when he was young, his parents argued for a long time. At that time, he also realized that he didn't only have one younger brother but also a younger sister.
It was a shock for him when they said that his sister is older than his younger brother.
Because he knew very well that when Nan Hua came to Nan Family, she was already almost one-year-old. At that time, she had learned how to walk on her own even if it was not very stable.
He thought his parents adopted a child.
But later on, he knew that they were his parents' child who were lost outside.
Even though the explanation was a bit strange, it was indeed the best explanation for a young 9-year-old child who didn't understand many things.
