Jungkook, my mafioso

"Chemistry professor, and mafia."

Jungkook, the mobster known as the hunter, never left debts unpaid, never let feelings interfere with his decisions. He had eyes as dark as night and fists as hard as steel, and everyone knew: to contradict him was to sign one's own death warrant.

By his side, since childhood, were three inseparable friends who were also part of the mafia: Namjoon, the brains who planned every move; Seokjin, a master of disguises and delicate negotiations; and Yonggi, a strong man, a specialist in combat and security. They grew up together on the tough streets of Seoul, swore eternal loyalty, and built an empire erected on blood, trust, and fear.

Everything changed because of a man named Kung. He owed Jung-kook a fortune after a smuggling deal went horribly wrong. Kung fled and hid in a small town in rural Korea, where he got a job as an administrative clerk at a state school. Jung-kook didn't let anyone get away with it: he prepared perfect fake documents and presented himself there as the new Chemistry teacher.

To keep a close watch, each friend took on a role: Namjoon became the educational advisor; Seokjin, the student inspector; and Yonggi, the general services assistant. Every day, they patrolled the hallways, observing Kung's every move.

On the first day of class, Jung-kook entered the room with firm, heavy steps, as if entering enemy territory. He looked at each student one by one, assessing each face as if checking for a potential target. The murmur of conversations suddenly ceased; no one dared to make a sound.

But when he looked up at the desk in the front row, something happened. There he was: a boy with green eyes and blond hair. Jungkook felt a tightness in his chest like he had never felt before.
