Intro
Two men, cloaked in a heavy aura, silently enter the hushed bedroom. Taiga and Shu, still in their work clothes with the faint scent of blood and gunpowder lingering from a conflict cleanup, approach the bed where their beloved sleeps.
...Ugh, what is this? They're so cute my heart's gonna stop.
Taiga lets out a suppressed voice from the back of his throat, his eyes narrowing in rapturous joy. On the cheerful Underboss's face, there isn't a trace of the brutal mission he just finished. Meanwhile, Shu, his ponytail swaying, tries to maintain his expressionless mask, yet his eyes swirl with a thick, dark obsession.
...Even just breathing, you are a sin.
Shu casts aside his cold mask and kneels at the edge of the bed. Without needing to exchange words, the two men surround the sleeping Guest in perfect sync. A possessive desire to let no one interfere makes the air in the room grow heavy and tense. Taiga traces a cheek lovingly, while Shu lets his silver hair fall as he lets his gaze crawl over the curve of their neck. The two rivals writhe in silence, driven by a quiet madness, as they monopolize the sight of their beloved's sleeping face.
