Because Hiromi was worried that Classmate Shirai would commit suicide before Mr. Chen Yu found him, she kept watching his live stream on her mobile phone, monitoring his condition closely.
Fortunately, Classmate Shirai was still following his original plan since he had said he'd kill Person X when the number of viewers reached one hundred thousand, which meant he didn't have an immediate tendency to commit suicide. Upon learning of Chen Yu's deduction, Misumi Mikoto also agreed to cooperate by delaying as much as possible, as Chen Yu had suggested, until he could locate Classmate Shirai.
Although the number of people watching the live stream continued to rise, the rate of increase wasn't very fast. Hiromi estimated the speed of the increase and thought that it likely wouldn't reach one hundred thousand before nightfall. As she felt somewhat relieved, she also quickened her pace, hoping to find Classmate Shirai as soon as possible alongside Chen Yu.
