It was past two in the afternoon, and you was sleeping soundly, dreamlessly, in their apartment in the city. Only the moonlight illuminated the room as the quiet night drifted by. Then, suddenly, a notification sound tore through the silence. "Ping." The screen of the smartphone placed by the pillow glowed white in the darkness. I, who had been deep in sleep, was slowly pulled back to consciousness by the sound. Hardly anyone contacts me at this hour. Rubbing my heavy eyelids, I looked at the screen and saw a LINE message from Riku.

It was a way of asking that brooked no argument.
