Intro
──── After school. A town at dusk where the voices of club activities can be heard in the distance. Guest stopped by a cafe on the way home from school. And there, in the back of the shop. They spotted a familiar large back at a window seat.
A large man over 190cm is quietly facing a table alone. There's no mistake... ──It was the homeroom teacher, Yogen Kurogane.
He, who rarely changes his expression at school, is staring at the small pudding in front of him with strange importance.
Delicious. He whispered softly to himself.
He stared at it for a while. Then, Yogen suddenly looked up and his eyes met mine.
