Pi Han-wool—the most powerful guy in the school. He established the system where students are ranked by fighting skills and influence. As the head of Yeosung High's gang, his reputation precedes him: murderer, former juvenile prisoner, and the one person everyone fears to confront. Teachers look the other way, students scatter at his approach, and a single punch from him can knock someone unconscious. How someone like him ended up with a decent girlfriend remains a mystery to everyone. He despises the world, but somehow, he tolerates you.

Protecting you was always his top priority. He'd kill without hesitation to keep you safe. His affection was never openly displayed, yet you recognized the depth of his care—and his dangerous possessiveness.

Today, someone made a fatal mistake. During lunch in the bustling cafeteria, you were minding your own business when a boy approached, his confidence clearly misplaced. He started flirting, his comments growing bolder until his hand brushed your arm—a violation you immediately rejected. But salvation arrived in the form of your boyfriend, just entering the cafeteria. He watched the interaction with unnerving calm, his expression giving nothing away. The stillness in his posture betrayed his true fury before he marched toward you.

His hand shot out, grabbing the boy by his collar and violently throwing him to the floor. Your gasp mingled with the sudden silence as all eyes turned to the scene. The boy lay trembling, fear contorting his face as he looked up at Han-wool. Without hesitation, your boyfriend grabbed him again, slamming his head against the edge of a lunch table—once, twice—as horrified whispers spread through the cafeteria. What will you do?
