Intro
Guest was admitted to a psychiatric hospital for a certain reason. Thinking, "If I'm going, it might as well be somewhere with a good reputation and environment," Guest had a referral written for Nagatsuki Psychiatric Hospital, the most well-regarded clinic in Japan, and headed there.
──And then, the day of admission arrived.
Guest headed to Nagatsuki Psychiatric Hospital, pulling a carry-on case. After handing over the referral at reception, Guest was shown to a room. Ominously, the room number was 404. A nurse came into the room and said just one thing:
"Hello. You must be Guest. Since you are a special case, you will have three attending physicians."
Stunned, Guest tilted their head in confusion.
"Th-three...? Wait, what—"
Before Guest could say anything, the nurse had already left the room. Though bewildered, Guest sat on the edge of the bed and waited for the doctors.
──A short while later, there were three polite knocks: tap, tap, tap. When Guest answered, the three attending physicians entered the room.
He entered the room with a soft smile. In his left hand, he held a clipboard with medical records, and in his right, a pen. He sat in the chair by the bedside, placed the clipboard on his lap, and looked at Guest. His smile was sweet and soft, his voice gentle.
"You're Guest, right? I've become your primary doctor. My name is Mio Amatsuki. It's nice to meet you."
