Night. Rain destroys the empty streets while police sirens echo through the city. Inside a crowded police station, officers whisper nervously as blood drips across the white floor tiles. A detective slams several photographs onto the metal table with frustration. Broken classrooms. Shattered windows. Students covered in bruises. At the center of every single image— Kim Taehyung Expressionless. Cold. His hands are stained red. The detective growls angrily, “All this… over one boy?” Silence fills the room. Another officer slowly places down one final photograph. A smiling transfer student with messy dark hair and dangerous eyes. Jeon Jungkook The atmosphere changes instantly. One officer whispers nervously, “That boy destroyed him.” Another shakes his head slowly. “No.” “They destroyed each other.”

Three months earlier. A peaceful classroom filled with sunlight, laughter, and ordinary students. Then the classroom door opens. And the moment their eyes meet for the first time— Everything begins falling apart.

Morning light spills across the classroom windows.

Students talk lazily. Chairs scrape against the floor.

Someone throws paper airplanes. But at the back corner—

Kim Taehyung sits alone beside the window, headphones on, eyes lowered. Untouchable.

The classroom door suddenly slides open. The teacher sighs.

A tall boy walks in with messy dark hair, hands inside his pockets, uniform half-open like rules mean nothing to him.

Jeon Jungkook

The room instantly becomes louder. Girls whisper. Boys stare.

Jungkook scans the classroom casually— Then pauses. Because someone is already staring at him.

Taehyung Cold gray eyes. Unmoving. Sharp enough to cut skin.

Instead of looking away, Jungkook smirks. Dangerous mistake.

The teacher points toward the empty seat beside Taehyung.

The entire room goes silent. Nobody sits near Taehyung Ever. Jungkook walks toward the desk slowly.

Step. Step. Step

Taehyung watches every movement carefully like he’s memorizing him already. Jungkook drops into the chair beside him carelessly. Their shoulders brush slightly. Taehyung's fingers twitch once. Tiny. Almost invisible. Jungkook notices anyway. Interesting. For the first time, Taehyung finally speaks.

Quiet. Flat. Cold.

Jungkook leans back lazily.

Silence. Then Taehyung turns his head slowly toward him.

Those emotionless eyes linger on Jungkook’s mouth for one second too long.

And Jungkook smiles wider. Because now he knows. The dangerous boy is interested.

The red mark on Taehyung's wrist grip remains long after lunch ends.

And Jungkook keeps staring at it during class like it personally entertains him.

Dangerous. Taehyung notices. Of course, he notices.

Everything about Jungkook has already started living inside his head.

The way he laughs. The way he taps his pen. The way his eyes narrow when he’s bored. It’s irritating.

The final bell rings. Students immediately crowd around Jungkook curious about the “new transfer student.” Questions. Laughter. Hands touching his shoulders casually.

Taehyung watches silently from his desk. Then one girl suddenly leans too close to Jungkook. Jungkook smiles politely. That’s enough. Taehyung stands.

The entire classroom quiets instinctively. He walks past everyone slowly before stopping beside Jungkook's desk. Cold eyes shift toward the girl.

The girl freezes instantly and backs away nervously. Jungkook blinks in surprise before laughing softly.

Taehyung ignores the question.

Instead, his gaze drops toward Jungkook's smiling mouth again. Sharp. Intense. Then he says quietly:

Silence. Jungkook tilts his head slowly.

For the first time—

Taehyung’s expression cracks slightly.

And Jungkook sees it.

Jealousy.
