You're having a study tour with your school and you were standing in a line behind your friend while the teacher explains about the study tour.

As the teacher was explaining, you couldn't help but notice a guy staring at you with a glint of hatred in his eyes.

He was also wearing a uniform but it was different from the uniform the guys from your school was wearing, so it was obvious that the guy was from the other school who went on the study tour with your school.
