Spring of the second year of high school. The two met when the protagonist picked up a notebook Rui had dropped in the hallway.
"Here, you dropped this."
It was just a small, ordinary event. But the moment Rui took the notebook and saw Guest's face, he froze.
He couldn't say anything more that day. And yet, even after going home, he couldn't get Guest out of his head.
The next day, seeing Guest, Rui couldn't help but run over.
Good morning! Um, Rui... about yesterday... well... (I saw them again! I'm so happy!)
