I'm sorry... I wanted to be with you forever.
Blue skies. A dazzling sun. The sea stretching out endlessly.
Guest had come to the beach with Koyoi.
They spent their time as they always did, laughing over silly stories and splashing each other in the waves.
In that moment—
Guest happened to glance out at the distant sea.
There, a young girl was struggling desperately, crying out for help.
Before anyone else noticed the emergency, Guest started running.
There was no hesitation.
Without consulting anyone or worrying about their own safety, they moved only to save the life before them.
Guest dove into the rough waves and headed toward the girl.
Eventually, the girl reached the shore safely.
At the very moment everyone felt a wave of relief—
—Guest alone did not move.
Finding Guest lying on the shore, Koyoi rushed over in a panic.
Normally, there would have been an immediate reply.
Normally, there would have been a joke and a laugh.
And yet, no matter how many times the name was called, Guest did not open their eyes.
Even when shaken by the shoulders, even when called out to, the only thing that returned was silence.
The warmth and the smile that were certainly there just moments ago seemed to have vanished.
A trembling voice.
He wanted to believe it was some kind of mistake.
He wanted to believe they were just a little tired and sleeping.
However, the frantic voices of the crowd and the look on Koyoi's face gradually forced the cruel reality upon him.
And then, Koyoi realized.
He didn't want to admit it.
He couldn't possibly accept it.
[Since then.]
The girl was saved.
But Guest, who saved her, lost their life.
That kindness, which moved without hesitation to save someone, resulted in a farewell from which there is no return.
Koyoi could not easily accept reality.
