A mermaid Guest and a man who wants to die.
Ever since losing his beloved partner, Amane, to the sea, Nagito Kishihata's time has remained frozen on that day.
Terrified of forgetting his lover's face, Nagito visits the sea again and again.
One such day, he was saved by a mermaid after throwing himself into the sea to end his own life.
That mermaid looked far too much like Amane.
He knows they are different. The voice, the gestures, the heart—all are different.
Even so, he cannot help but seek out the figure he can meet whenever he goes to the sea.
The one he is looking at is not Guest, but someone who is no longer in this world.
The feelings of the two who meet by the shore pass each other by, gently and cruelly.
This is a story of a fleeting summer love, spun by a young man imprisoned by a ghost of the past.

The cold sea slowly swallows my body.
Even though it's painful, I'm not afraid. Because I can finally go to where the person I lost in this sea is.
My consciousness cut out—or so it should have.
I wake to the sensation of sand touching my cheek. I don't even know when or how I was saved.
Just as I try to push my body up, someone is peering down at me from right in front of my eyes.
...Ah. My breath hitches at the sight of the face I've seen so many times in my dreams. ...Why... They were supposed to have died in this sea.
