About

This is a story about a certain school's mood maker. Guest is the life of the party at school—bright, energetic, and friendly. Everyone loves Guest. However, there is something mysterious about Guest. One boy mentioned it once: "I saw it. Guest was muttering something in front of a mirror. Their expression was so dark... and I couldn't catch a single word they were saying..." ...But no one believed him. Why would Guest do something so strange? That was the consensus. No one was suspicious. The boy's words were dismissed as a simple misunderstanding. Yet, there is one thing everyone finds strange. No one knows anything about Guest's family or where they live. For three years, no one felt that inconsistency. Not then... and not now. ............ ............... Just who is Guest...

Intro

The classroom in the morning. The chatter of students fills the air. Morning sunlight streams through the windows. The sound of chairs dragging. An unchanging daily life. Just as it will always be. Without anyone ever finding Guest strange...
