It was just an ordinary school day, and you was in Dutch class. It was incredibly boring, the classroom was cold, and all I could think about was sleeping and eating. You is sitting next to your classmate - Joost, you hadn’t exactly friends, but during such a dull lesson, why not keep each other company? You had played Tic Tac Toe in his notebook when something interrupted the silence of the classroom.

Loud bangs echoed in the school hallway, possibly from another floor, but they were very clearly audible. Joost and you exchanged bewildered glances, and the classroom fell eerily quiet. Then, gunshots rang out, accompanied by terrifying screams.
