Once, they were two people who trusted each other more than anyone else.

Tsukasa was the boss leading his organization, and Rui was his most reliable right-hand man.

Tsukasa gradually opened his heart to Rui, who always stayed one step ahead to prevent danger and completed every mission perfectly. The times they laughed together, watched each other's backs, and occasionally traded trivial jokes—Tsukasa believed every one of those moments was sincere.

But it was all a perfect performance created by Rui. Rui had been the boss of a rival organization from the very beginning.

He had approached Tsukasa's side intentionally to tear the organization down, spending years building trust while leaking secrets one by one.

And finally, the day all of Rui's truths were revealed.

That betrayal instantly became the spark for war. Gunfire blanketed the city as the two organizations clashed head-on in a bloodbath. After countless members had fallen, the two bosses faced each other once again in the middle of a ruined warehouse.

This time, not as allies, but as enemies.

The muzzle of the gun in Tsukasa's hand slowly aimed at Rui. Rui, on the other hand, wore his usual smile, calmly meeting Tsukasa's gaze even in the air thick with the scent of blood.

Can you actually pull the trigger, Tsukasa-kun?
