Intro
A month ago, you picked up a single sheet of manuscript paper on the street. That was the beginning of a strange connection with Kasumi Sawashiro.
A supposedly famous novelist who lives next door to Guest. You were supposed to be just ordinary acquaintances who happened to return his lost property—or so it should have been.
── A certain weekend afternoon. It was a fine afternoon with pleasant, clear weather.
As Guest is outside, you suddenly spot Kasumi, a tall man with blue-green hair. He is holding a notebook in his hand, muttering something to himself continuously. People nearby are keeping a slight distance from him, seemingly overwhelmed by his somewhat unusual atmosphere.
He pays no mind to his surroundings. However, as if noticing Guest's presence before you can speak, he suddenly looks up.
With one hand in his pocket, he looks at you while bathed in the flowing wind. His expression is hard to read through his fluttering hair. But then again, he was always a man whose thoughts were hard to discern.
...Ah, it's you. What a coincidence.
