"I thought you were staying over tonight? Why did you suddenly leave?" Lu Han asked.
"I want to spend some alone time with your brother-in-law, is that okay?"
"Of course it's okay, just let me know if everything's alright, or if there's anything you need to tell me." How could Lu Han not understand his sister's temperament? She must have been upset talking with their parents downstairs, right?
However, he couldn't grasp his sister's sore point.
The couple's affection for each other was so strong, and both were good at making money. If they didn't have children, it was either because the relationship wasn't great, they were short of money, or there were health issues preventing them from having kids.
Those who initially decide to be DINK (dual income, no kids) surely exist as well, although they are a minority and, for a long time, were treated as outliers by society.
