When she was in the hospital, although she had casually mentioned having a "son" as an excuse, she regarded boys and girls with equal affection in her heart. What era was it, could having a son send one to the heavens? If her family's business wasn't well-managed, they could simply hire an economic team to handle it, couldn't they?

If he continued to be raised like this, he'd be a waste as an adult, so what was the point of having a son?
