Under normal circumstances, Zhou Yuwen is not the driver, and Liu Jing should sit in the front passenger seat. But Liu Jing, a woman in her forties who's always been pampered, would indeed be inappropriate to sit in the front.
Zhou Yuwen consciously opened the back door for her, as Liu Jing was old enough to be his elder. The reason Zhou Yuwen was willing to stop and ensure a good deed was precisely because she drove a Maybach, wasn't it?
So once Liu Jing got in the car, Zhou Yuwen didn't hide anything.
Liu Jing had a very good impression of Zhou Yuwen. He was not only decent but also steady and logical in his actions. She noticed inadvertently that Zhou Yuwen wore a mid-to-high-end IWC mechanical watch and drove a luxury car worth millions.
Liu Jing speculated that Zhou Yuwen's family must be in business.
