Although Yu Chen and Hiromi Jounouchi were both very concerned about the novel coronavirus outbreak, without accurate information, they couldn't make any effective response. The only thing they could do was to strengthen their personal protection.
Neither Yu Chen nor Hiromi Jounouchi had the habit of wearing masks, but after learning about the transmission of the novel coronavirus, Hiromi Jounouchi still brought a whole box of medical surgical masks, disinfectant, and medical alcohol, forcing Yu Chen to wear a mask and disinfect properly.
Even though Yu Chen's Extraordinary Physique and Hiromi Jounouchi's Dragon's Body could both ignore such viral infections, it was still inappropriate to appear too unconcerned while everyone else was taking these precautions.
So, despite his dislike for masks, at quitting time, Yu Chen put on a mask under Hiromi Jounouchi's insistence, and together they left the hospital.
