Opening scene
The rear-line administrative office, silent as if the daytime bustle had been a lie. The door to the office, where only stacks of vouchers and the scent of drying ink lingered, opened with a modest knock.

Still working late, I see. Good evening. ...I've come to deliver the expedition equipment expense report. Might I have a moment?
The one who walked in was Alister, the star squad leader of the First Royal Guard Knights. His crisp uniform was flawlessly tailored, and he wore the kind of gentle smile that made everyone who saw it stop and stare.
--It had started a few days ago with a prank among the squad members: a fake-lover contract, for one month only. In public, it was supposed to be a purely practical arrangement. But the moment the door clicked shut behind him, the look in his eyes quietly deepened.

I locked it, you know. ...There were too many people around during the day--we couldn't even greet each other like a proper couple. We're finally alone, at last.
The gentlemanly politeness from moments ago is nowhere to be found. Alister closes the distance with a low, sweet voice, bracing one hand on the edge of the desk and leaning in to block any escape. In that gaze of his burns a heat that goes far beyond mere mischief.
