The Auction House—a massive auction site that appraises, protects, and trades "Value."
Brilliant lighting. Deep red carpets. Walls adorned in black and gold with theatrical decorations. Beyond the glamour, heavy iron doors and grates peek through, telling of a place that protects what is valuable while ensuring nothing escapes easily.
On that day, a single "product" was brought in.
No name tag, no gaudy decorations. Clad in humble clothes, Guest was housed in the facility as one of the items to be appraised for Value.
And then—before the appraisal could even begin, an incident occurred.
You look around restlessly. Eventually, your gaze stops. Something is wedged in a gap of a strange decoration.
What's that?
You step closer and peer in.
Noticing the movement, Robert's eyes widen.
Hey, wait—!
Clang!!
It happened almost simultaneously with the warning.
A part of the decoration that seemed to have been there for years came off easily and fell to the floor. The heavy-looking component rolled away with a strangely nonchalant sound... clatter, clatter...
Silence falls over the area.
Huh?
You look at the decoration that fell and rolled away.
♠ Valdo
He finds the JOKER who had wandered into a restricted area. After watching in silence for a while, Valdo walks up, grabs them by the collar, and pulls them back.
...Hey.
His blue eyes look back and forth between the JOKER and the open door. He doesn't shout, nor does he panic.
I did say you could "look around as you please."
This area was not included.
He leads them to a safe corridor and finally lets go. He lets out a small sigh.
So?
He returns only his gaze to the JOKER.
What did you find this time?
♥ Elliot
Elliot finishes his conversation with a client with a smile. As soon as the person leaves, he turns his gaze to the JOKER nearby.
Oh. You were watching quite intently, weren't you?
He smiles teasingly, resting his chin on his hand.
Do you want to know how to make someone fall for you?
He stops with his smile fixed at the response he gets.
............
No. That's what you were curious about?
The smile that was perfect until a few seconds ago falters slightly. Eventually, he can't help but shake his shoulders.
Hehe... You really never end up where I expect, do you?
Fine. Shall we talk about that instead?
