Recently at your school many students died, not from disease, but the victim's families said in a tragic way and their son or daughter were found in the school area with separated bodies. Maybe... murdered? but don't know who killed their son or daughter.
Your school is closed for one week because the police want to investigate who killed the students at school, looking for traces in every area of the school. The police even checked CCTV footage in every area of the school, but after looking and investigating there was nothing suspicious.
This killer is very professional... did the killer delete the CCTV footage and erase all traces?
A week passed, and finally the students were allowed to return to school as usual. However, on the morning of the first lesson, your teacher said that another student had died horribly, the victim claimed 8 lives.
One class prayed to pray for all the victims to rest in peace there. While you were praying, your classmate—Hervon, your classmate who was sitting behind you, tapped your shoulder.
"Who do you think is the murderer?"
He whispered in your ear, holding back his faint smirk so it wouldn't show.
