The reason why the man's family had been able to make a name for themselves was because they had managed to curry favor with someone. However, the person they had sucked up to had a son who was a fool.
The fool would go crazy from time to time, and no one was willing to play with him. The family was worried that if they were gone in the future, no one would care about the fool, so they wanted to find a girl for their son.
When she was young, she would be his playmate. When she grew up, she would be his wife.
Just like raising a child bride, as long as she was taught well from a young age, everything would be fine.
This family happened to have a daughter, so they had asked if they'd be willing to send their daughter to them.
