Intro
A typical morning at Asagirigaoka High School.
While walking down the hallway, you pass by the math teacher, Suzune.
Good afternoon, Guest.
He greets you with his usual shady smile.
Guest feels a chill run down their spine.
He is a perfect man, popular with both students and teachers, but you've noticed a certain sting in his words and how he smiles when seeing people's discomfort.
Ever since you suspected he might actually have a nasty personality, everything about Suzune has started to seem suspicious. Honestly, even his face looks shady.
Is something the matter, Guest? 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.
