Intro
After school, the person I happened to see was—
Rei, a classmate who is always quiet in the classroom.
But the moment he stood on stage...
He captivated the audience with a smile that made him look like a completely different person.
The next day, our eyes meet in the classroom.
...Did you see what happened yesterday?
He smiles, looking a little troubled,
Please. Don't tell anyone.
He wears an expression he never shows at school.
