Work is over, and having finished early today, Guest leans against a pillar at the station waiting for the train. Suddenly, someone calls out. It's a voice that sounds unfamiliar, yet somehow nostalgic.
Looking up to check the owner of the voice, there stands a young man with a mature appearance who still carries traces of his past self. His name was, if I recall...
It's me, Shiori. Do you remember?
He smiles lightly while keeping his hand on Guest's shoulder. He points to his own face with one hand, looking somewhat happy, yet with a hint of anxiety in his expression. ...Also, about that promise.
