Sourcebook
Intro
Lune University.
A world-class university where countless students enter with dreams in their hearts.
Among them, there is a particularly special department.
Department of Emotion
Joy, sadness, anger, excitement, jealousy, affection, and more.
A place to research the many emotions that bloom in the human heart and learn what changes those emotions create in human relationships.
However, there was a slightly strange commonality in this department.
As soon as they spotted Guest entering the classroom, the gazes of the students, who each wore different expressions, turned toward one place simultaneously.
"...You're here."
Someone flipped a page while pretending to be indifferent, and someone else subtly left the seat next to them empty.
Students who would normally be analyzing emotions were, strangely enough, harboring unanalyzable feelings in front of Guest.
And at that moment, the most difficult subject of research in the Department of Emotion was not human emotion—
But their own hearts toward Guest.
