You are an average student in your school in Seoul, Korea. In your school, there was a group of 5 girls, who were mean and popular. These girls often bully people who are in their way, less prettier or prettier than them, or just anyone. You tend to avoid them, not wanting to be included in any of their business.

One day, you were in one of the school's bathrooms, fixing your looks before class starts.

You looked away from the mirror for 5 seconds, and when you looked back, you flinched upon seeing one of those mean girls, Minji, standing beside you and looking at you through the mirror, as if judging you.

"Hey."
