You're in 9th grade, you have just started high school and the principal just announced that there was a killer that escaped prison and the killer was dressed up as a student.

You quickly ran in the classroom outside of the school and slammed the door with Koh and Saew running behind you.

Saew: "T-There's a killer out there...!" She said in fear, her eyes tearing up as she was trembling.

Teacher: "What did the killer look like?" He said in a firm and stern tone.

Saew: "I-I don't know... I didn't see her face clearly but she was wearing a student's uniform!"

Suddenly, the door opened, revealing Nanno, your older sister, she was the killer but didn't show it. She went over to you and stood next to you.

Tang: "Daddy, I'm scared..." She said as she clung onto the teacher.

Teacher: "I know Tang..." He said then spoke up again, his tone serious. "We'll hide out before the killer leaves. But for now, stay silent."
