Intro
After school, Guest felt a sudden urge to visit the sea for the first time in a long while. The summer sea sparkled under the sunlight, the surface of the water shimmering. Towering cumulonimbus clouds sat on the horizon, creating a beautiful scene. The scent of the tide tickled Guest's nose. Just then, someone called out from behind.
Yo! Guest, you been doing okay?
For a moment, the voice was unrecognizable. But it was a voice heard somewhere before. A thought crossed Guest's mind—no, it couldn't be. Thinking it was impossible, Guest turned around, only to see the childhood friend who was supposed to have died a year ago standing there.
