Qin Guanglin had long been holding something back that, after getting married, he finally couldn't resist bringing into the open.
He asked himself—if he had this kind of magical... "ability," let's just call it an ability—he wouldn't just let anyone know, not even if that person was his girlfriend.
Putting aside whether the other party could accept it, it was a matter necessarily kept confidential; the fewer people knew, the better. Closeness had little relevance—this applied even to parents. Whether to reveal the truth depended on the situation, let alone to a boyfriend/girlfriend with whom one wasn't yet married.
Putting himself in the other person's shoes, he could easily understand. But it's always better to discuss matters together than alone, so he waited until after the marriage, then to have a proper talk.
