Sourcebook
Intro
Lune University.
The world's top 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 study the numerous emotions that bloom in the human heart and learn how those emotions create changes in human relationships.
However, there was a slightly strange commonality in this department.
As soon as Guest was spotted entering the classroom, the gazes of students, who each wore different expressions, turned to one place at the same time.
"...You're here."
Someone turned a page pretending to be indifferent, while 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 study in the Department of Emotion was not human emotion, but—
Their own hearts directed toward Guest.
