That night, the sky looked heavy-dark clouds hung low above the city . On the empty streets, the rumble of motorcycles echoed in the distance, breaking the silence with deep, commanding roars. Streetlights reflected off the wet asphalt, illuminating a group of riders dressed in black jackets bearing the same emblem — ATEEZ. At the very front rode a man on a matte-black bike, his full-face helmet concealing most of his features, yet the aura he carried was enough to make anyone hesitate to look directly at him.

He was Choi San, the leader of the ATEEZ motorcycle gang. A figure both feared and respected in the street world. Known for his strictness, near-flawless leadership, and eyes cold as steel. San was never one for chaos. ATEEZ might have been a biker gang, but under his rule, they had never been involved in crime. He disciplined his members like a stern father- forbidding them from hurting the innocent, disturbing the public, or doing anything that would stain their name. Still, discipline was never easy. Many young bloods burned with pride and recklessness, forcing San to step in whenever ATEEZ's reputation was at risk.

But tonight was different. San wasn't out patrolling to defend his gang's honor. He had another mission... something that even he couldn't fully explain why he cared so much about. It all started with his younger sister's story. About a high school girl, her friend who was being toyed with by the leader of BOUNCY, a rival biker gang. That news made San's blood boil. He knew exactly who BOUNCY's leader was... a sly player who loved using women for fun and bragging about his power. And now, that man dared to touch someone so young, so pure. San couldn't just stand by. This wasn't about gangs or pride anymore, it was about something far more personal... justice, in its rawest form.

As the night grew darker, ATEEZ stopped in front of an old warehouse, BOUNCY's base. One by one, the engines went silent. San stepped off his bike, removed his helmet, and stared at the building with a cold, unblinking gaze. The night wind swept through his black hair, and in his eyes burned a restrained fury. From the shadows, BOUNCY's members began to emerge, laughing mockingly, unaware that a storm had just arrived at their doorstep. San walked forward slowly, every step radiating both control and danger.

"Tell your leader…" His voice was deep and calm like the whisper of a coming storm. "I'm not here to play games. Tonight, I'm taking back something that should've never been yours."
