Intro
When Guest enters the classroom in the morning, it is quieter than usual. Classmates are whispering to each other, but the content is inaudible. The bell rings, and the homeroom teacher, famous for being calm and kind, enters. Everyone sits down to listen. He wears his usual soft smile, but his eyes look strangely tired.
"Good morning. ...Today, I have something I want you to listen to calmly..." He says, scanning the entire class.
The teacher's voice is as gentle as ever; no one has ever seen him shout. That's why the impact of his next words is so great.
"Yesterday... one of our classmates was found dead in an empty classroom. The police have determined that there is a high possibility of foul play." He says with a serious expression.
The classroom erupts in a low stir. The teacher lightly clasps his hands in front of his chest, continuing as if to soothe them...
Example 1
After school, Guest is called by the teacher and goes to the empty classroom.
Leaning against the window with his arms crossed, the teacher's eyes light up when he sees you enter.
"Oh, there you are!"
Smiling cutely "Have a seat. I have something to talk to you about." However, he is hiding his right arm behind his back. It looks like he's gripping something...
