UNWRITTEN LESSONS | JINKOOK

CH1

Mornings at the high school were chaotic for most students. The hustle and bustle filled the corridors, conversations intertwined with laughter and complaints, and the echo of hurried footsteps reverberated through the hallways as everyone tried to reach their classrooms before the dreaded start of lessons. However, for Jin, things moved at a different pace. He walked nonchalantly, with relaxed steps and a gaze that seemed to float above the urgency of others, as if none of it had anything to do with him. For the blond, school was a place to pass through, a stage where he merely played the role assigned to him: the troublemaker, the one who wasn't afraid to challenge the rules, the teachers, or even himself.

With his backpack carelessly hanging from one shoulder, his uniform wrinkled, and his hair tousled by the morning breeze, Jin walked towards the classroom, fully aware that he was already late. He didn't care. Even with a small bandage on his cheek, a reminder of a recent fight, his attitude remained the same: disinterested, cold, and haughty. He didn't seek attention, but he got it, and he knew it. Each of his steps echoed in the empty hallway, a rebellious sound that made it clear he wasn't in a hurry or worried.

He pushed the classroom door with unnecessary force, producing a loud creak that made everyone look up from their books and stare at him. The room, which had been silent until that moment, filled with murmurs. But Jin was unfazed. There was nothing in the inquisitive looks of his classmates that could bother him. In fact, he seemed to enjoy that little interruption. However, something was different that morning. The usual maths teacher wasn't there. Instead, a young man with wavy, jet-black hair, a rigid posture, and a severe expression was watching him from the front of the classroom.

"¿Who are you?" the man asked in a firm voice that showed his annoyance at the interruption.

Jin looked at him with a mocking smile, tilting his head slightly as if assessing the situation. There was something in the way the new teacher looked at him that made him feel the need to provoke him.

"I should be asking you that. Where's the old man?" he replied, dropping the words with disdain as he walked slowly to his seat, showing not the slightest sign of respect.

The new teacher's eyebrows furrowed even more, and he crossed his arms over his chest, clearly irritated. "Don't be disrespectful," he warned, with a tone that tried to be authoritative, though with a slight tremor that betrayed his lack of experience.

Jin watched him, and a low laugh escaped his lips. "Whatever...," he said as he dropped into his seat, looking at the teacher with a mix of defiance and boredom.

"¿Where do you think you're going?" the man asked, his tone hardening, trying to regain control of the situation.

"To my seat, ¿are you blind?" Jin replied, enjoying the slight murmur from his classmates, who were watching the scene with a mix of tension and entertainment. The new teacher seemed to be an easy target, someone he could play with for the rest of the term.

The teacher, whose name Jin still didn't know, stared at him for a moment, clearly struggling to maintain his composure. It was his first day, and he already had to deal with such a troublesome student. Finally, he took a deep breath and continued.

"Listen carefully," he said in a cold but controlled voice. "Next time you're late, you won't be allowed into the classroom. ¿Is that clear?"

Jin shrugged, dismissing the teacher's words. He knew how to handle teachers. None of them dared to really confront him. His indifference only fueled the man's frustration.

The teacher cleared his throat and, with visible effort, tried to continue with the class. "As I was saying before your classmate's interruption," he resumed, now addressing the group in general, "my name is Jeon JungKook. From today, I'll be in charge of your maths classes."
