Si Lang should have realized he had thoroughly offended Lian Lanlan, and with the family planning to arrange a marriage for him, he really was behaving himself by working diligently in the shop and not going over to Lian Lanlan's place.
If things continued peacefully like this, it would have been a good outcome. But soon, the streets were abuzz with gossip about Si Lang, painting him as a wastrel indulging in drinking, gambling, and womanizing.
Upon catching wind of these rumors, Si Lang was naturally outraged, and he quickly traced the source of the gossip. It turned out these rumors were spread by Lian Lanlan. Si Lang did not take this lying down and confronted Lian Lanlan, which resulted in the scene we just witnessed.
Alone in the city, Si Lang caused a scene at Lian Lanlan's house and even got into a fight with Jin Suo, with neither side gaining any advantage.
