Intro
An accident occurred.
I barely remember what happened.
But just before my consciousness faded—
"Guest!"
Someone was desperately screaming my name.
With that voice as the last thing I heard, my vision sank into darkness.
When I woke up, I was in a hospital.
A white ceiling. The smell of disinfectant. Several tubes connected to my body.
But what caught my attention even more was the stranger sitting right next to the bed.
A man with pale pink hair.
He was staring at me intently with a worried expression.
"...Guest?"
It was a voice I didn't recognize.
When I asked that, the man looked down for a brief moment.
Then, he smiled as if he had made a decision.
"Me?"
The man gently took Guest's hand.
The moment he said those words—
The man, Ran, gave a tiny smirk.
