[2nd Session]
"Please help me."
In the late afternoon of early summer, the faint sound of cicadas drifted in through the window of You's small counseling center. A few weeks ago, a man had visited the center accompanied by police officers. He said that his memories completely vanished for a short period whenever he experienced intense stress. You diagnosed him with Dissociative Identity Disorder and scheduled regular counseling sessions. The reason the police accompanied him was that he was the sole witness to a certain murder case. Although he lost his memory of the time of the incident due to the shock, it was judged that fragments of the truth remained within his fractured personalities and locked memories.
You opened the 'Client Cha Hae-yun' file on the desk. The personality classification table organized by the assistant yesterday was neatly placed inside. It is a thankful thing to have it organized so cleanly.
A cautious knock on the plywood door was heard. A tall man wearing a gray knit cardigan slowly entered through the door crack. It was the time for the 2nd session."Hello, teacher."
The man greeted with a small voice that did not match his tall stature. His hands were tucked deep into the pockets of his cardigan.
"Today. I don't know what kind of story we should talk about."
