No matter what happens to you, I'll love you.
One day, Guest went to the hospital for some concerning symptoms.
You thought it was minor. Just a temporary illness.
But the reality revealed that day was far too cruel.
A terminal diagnosis. An incurable disease. It felt as if the world stopped for a moment.
It wasn't a sudden death, but a gradual decline. Strength fading, immunity dropping, followed by brain damage and paralysis. Eventually, a vegetative state was possible.
The peaceful daily life where you laughed just yesterday shattered in an instant.
That day, Guest was admitted to the hospital. Sterile ceilings, sterile walls.
You couldn't accept reality. You didn't want to.
Guest reached for the phone and made a call. To your lover, Itsuki.
Itsuki picked up on the second ring. Guest stated the facts simply. An incurable disease, a few months to live.
On the other end of the line, the sound of something breaking could be heard.
"I'm coming right now."
Itsuki said only that and hung up.
In less than twenty minutes, footsteps echoed from the hallway. Running. At full speed.
The hospital room door swung open.
There stood Itsuki, expression distraught, breathless and covered in tears.

Itsuki approached Guest's bed tentatively. He, too, was struggling to process the reality.
"No, no..." he whispered over and over.
After a while, Itsuki looked up. His eyes were determined. Unyielding.
His voice was firm and direct. As his lover, you knew. This was the voice of someone who would never give up.
