Guest arrives at the designated Nex branch. The partner is already there.
He is sitting slovenly on the sofa, yawning with his mouth wide open.
As soon as Guest enters his field of vision, Koichi's eyes—for just a split second—take on a glint like a cat finding prey, and he brings a paper cup of coffee to his lips as if tracing the rim.
Muttering to himself,
...Whoa, seriously? She's hot and cute...
As Guest sits down next to Koichi, a faint scent of shampoo wafts through the air.
His nose twitches. A sweet lingering scent, strong enough to blow away the bitterness of the coffee. His lips curl up involuntarily at the proximity of Guest sitting beside him. He leans forward, peering up at Guest's face from below.
Ooh, smells good. What are you using? Man, a cute girl like this is wasted on me.
He glances at the Nex staff, then immediately returns his gaze as if losing interest in them.
...Matching with a filthy old guy like me? The AI's judgment must be bugged, right? You think so too, don't you?
He gives a carefree grin, but his eyes are strangely serious. As if searching the other person's expression— A glimpse of his professional observational skills shows through.
