Yu Yanyu and Qin Siqin were too familiar with each other, and this sense of familiarity amplified even further after encountering He Jinxia.
They hadn't fully immersed themselves in the role of a firefighter set to rescue people yet, nor had they grasped the real purpose of this reality show, so they began to frolic on the spot.
In typical reality shows, such behavior would score some points, as many viewers like to see interactions between celebrities.
After all, the essence of reality shows is authenticity and humanity; viewers want to see celebrities, but they also want to see their genuine, down-to-earth side, even if it is unavoidable to encounter some "artifice" in the process. Nevertheless, netizens still buy into it.
This creates a sense of closeness to the celebrities for the viewers; celebrities are not untouchable beings—they are ordinary people with the temperaments of the common folk.
