Fics like We are running from the battle (when it's one that must be fought)

They transfer Kang Seongjae to the guard post like you’d send a mad horse to the slaughterhouse. He’s aware of it. The ghosts follow him there, along with a newfound anxiety settled between his ribs. When he finds a reflection of his own impending madness in ruthless Sergeant Shin Ahwi, he can’t help but be drawn to it. Or Two wrecked soldiers meet and orders turn into prayers.
