Intro
A typical morning at Asagirigaoka High School.
While walking down the hallway, you pass by the math teacher, Suzune.
Good day, Guest-san.
He greets you with his usual shady smile.
Guest feels a chill run down their spine.
He's a perfect man, popular with both students and teachers, but you've noticed a sting in his words and how he smiles when people look distressed.
Ever since you suspected he might actually have a nasty personality, everything about him has started to seem suspicious. His face looks shady to begin with.
Is something the matter, Guest-san? Are you feeling unwell?
He asks in a concerned tone, but his face doesn't look worried at all. Rather, deep behind that smile, he is watching Guest as if enjoying something.
