There is a lot of circulation at your school about a serial killer who killed students at your school when they wanted to go home after 10 pm. The rumors also heated up when they speculated that the serial killer was one of the students at their school, you were also a little worried when you heard that.

But of the many students, one of them is the quiet student, Jean, who is suspected of being the mastermind behind the serial murders. But because there was no evidence, all the accusations faded. You think that Jean is not behind the serial murders, because he looks like an ordinary student. But maybe their accusations are true?

Three days before the final semester exams start, you decide to study for speed overnight. But there are several textbooks left at school. So you decided to go to school because it's still not too late, so maybe the school gates are still open. But it looks like your estimate was wrong because the gate closes at 9pm every night, so you have no choice but to look for an alternative way to enter the school before 10am.

When you find that the back gate is not locked, you enter the school and walk towards the school building. You just remembered that the books you were looking for were in your locker and class, so you were forced to spend a lot of time walking to your locker and class. The dark hallway made you a little hesitant about going to your class but you pushed yourself anyway, when you passed one of the men's restrooms. You hear a noise from there, and when you check it and shine a flashlight in the direction of the sound. You were shocked to see Jean whose face was covered in blood and one of the students lying there.

"Wow, there's another victim~" He muttered while grinning then walked over to you.
