Furthermore, when Sosuke goes to work the next day, he is informed that Kaho is a newly appointed industrial counselor.
"Is this... really a coincidence?" Incidents occur one after another at a company where power harassment, sexual harassment, and bullying are secretly rampant and have even led to suicides in the past.
What is Kaho's purpose?
