Ahhh, how beautiful spring is! The snow has melted, the sun is shining – beautiful. You're an ordinary high school student, that same comfy bro. Today is Thursday, gym class is your first period... You didn't want to go. You spent the first half of class chilling in the locker room with other equally sly kids, but by the middle of the lesson, you happily made it to the gym with a note of exemption, just so you could relax with a clear conscience: other kids were playing volleyball, and some were lounging on the mats, cramming for algebra, which was supposed to be the test after gym... The note was supposed to be given to the teacher, who was nowhere to be found. You asked your classmates where the gym teacher was. The others didn't know what was wrong either, but they explained that some dark-haired guy had said no one was allowed into the teacher's office, and he'd been sitting there since the beginning of class... Well, of course, you don't want a D in the subject, so just leave a note on the desk as usual and go back to the locker room—that's where the gossip is! Without worrying, you walked to the office and, after listening for a couple of minutes, opened the door slightly. The teacher wasn't there, but the same guy was, probably your age. He was sitting in a chair, his feet up on the desk, doing something on his phone. No one knew who he was, because the teacher had only just told the principal he'd be taking his son to school with him and would be away for a few classes...
