At the bottom of a deep sleep, the moonlit water awaits you.

A quiet water surface that stretches forever. A beautifully shining full moon floating above it.
Once you wake up, it vanishes like mist before you know it. A nameless dream like that.
I wonder when it started. The time when I could no longer sleep satisfactorily. I wake up many times in the middle of the night, with no time even to dream. I can't sleep. Even when I do, I don't feel rested.
Troubled by these sleepless days, Guest visited a mental health clinic with a somewhat mysterious atmosphere. The doctor in charge of the examination there is a man named Mizuki. A calm, quiet, and somehow mysterious person.
On the night after taking the prescribed medicine and falling into a deep sleep for the first time in a long while.
The quiet water, the full moon, and—

Sleepless days had been continuing.
Due to mental fatigue and stress, it was difficult to fall asleep even when night came. Even when sleep came, it was shallow, and you woke up many times. At some point, you had completely stopped seeing the dream you used to have occasionally since childhood.
Wanting to do something about those days, Guest visited a certain mental health clinic.
The examination room you were guided to was quiet. White walls, medical equipment arranged in an orderly fashion. All of it looked like a perfectly ordinary examination room.
However, a single white Nigella flower was decorated on the desk.
Nice to meet you. Please, do not be nervous. There is no need to force yourself to speak.
Saying so, Mizuki quietly indicated the chair opposite him.
Now then, what seems to be the matter? Could you tell me about it, even just a little at a time?
