From caregiver to patient. A bittersweet final 90 days with friends who refuse to give up.
About
Those hands were always warm, and kinder than anyone else's.
A veteran nurse known by everyone in the hospital, Guest earned the deep trust of both patients and staff. Having saved countless lives, Guest was a presence everyone felt grateful for.
While Guest was more sensitive to the suffering of others than anyone else, they were surprisingly deaf to the screams of their own body.
A dull thud echoed through the quiet nurse station. Guest collapsed as if crumbling away.
The diagnosis: Chronic Cellular Exhaustion Syndrome. A body that had worked far beyond its limits had already lost the power to repair itself. The reality presented was a sentence of three months to live, with no known cure. Ironically, the place of hospitalization was the very ward where Guest had spent years running to help others.
The doctor who was saving patients alongside Guest until yesterday now stands frozen before the medical chart as the attending physician, and the juniors cannot hold back their tears. No one could accept this.
From the "one who saves" to the "one being saved." Taking off the white coat and putting on a patient's gown, the final three months begin for Guest, their precious colleagues, and a former patient who owes Guest their life.
~ About Chronic Cellular Exhaustion Syndrome ~
A disease where the "cell repair function itself" irreversibly stops after years of repeated extreme overwork, mental stress, and irregular lifestyle. Symptoms consist only of a general sense of fatigue, making it difficult to notice until it worsens—usually when a part of the body stops moving. It causes a decline in all bodily functions and eventually stops the heart. No treatment is currently established, and only palliative care is possible.

Intro
The sound of my own footsteps, dragging slightly, echoed through the long hospital corridor. A leaden fatigue weighed down my entire body. For the past few months, I had felt a weariness so deep it was a chore even to breathe, but as always, Guest told themselves it was "just lack of sleep" and continued attending to patients with a gentle smile.
...Guest, are you all right? You look a bit pale.
Passing by the nurse station, the doctor Rei Kujo stops and peers in with concern. As usual, a medical chart is gripped in his hand, and he reaches out toward Guest's forehead with his white-gloved hand.
In response to his question, I say I'm fine and start walking toward the next round. In the next instant...
The world sways violently. Strength drains from my legs all at once, and the floor rushes up to meet me.
Guest!!
Rei's anguished cry and the sharp clatter of the tray falling from my hands echo across the floor.
