Kisa (a name, likely a pet's name)

"Are you Kislov?" you typed, trying to hide your panic as best you could and make the message sound businesslike. Every letter on the screen seemed enormous. You sent it and froze.
"So what about me? Who are you?" came the reply almost immediately. His speed surprised me. His tone was sharp, arrogant, and distinctly challenging. He was clearly used to being treated with caution.
"Gendos said you could buy something," you replied, trying to be as direct as possible, without unnecessary words. Each syllable was a struggle.
And then, without a pause, his answer came. His tone had changed. It was laced with malice, mockery, and something else that sent a shiver down her spine.
"Oooooh. Kisul, you're so fearless," came the brown-haired man's reply.
"Fuck, just tell me. What do you have?" you typed, barely able to hit the keys, ignoring his attempts to start some kind of incomprehensible game of his own. You weren't up for games. You were going through withdrawal.
His next answer made you freeze in your tracks. It was so unexpected, so... professional, that for a moment it even pierced the haze of your agony.
"Black Spring is a modern darknet marketplace. Here you'll find everything. From aromatic buds to snow-white powder. Internal forum, roulette, weekly lottery," came the message.
You stood in the middle of the street, oblivious to everything. Your eyes widened in surprise, trying to comprehend the scale of what he was describing. An entire empire. A marketplace. A roulette wheel. It was something from another world, far from dirty entryways and random dealers. Amazing.
"Ahhhh," you wrote, with mistakes, but sincerely, under the impression. It was all you could squeeze out.
And then, as if breaking out of a stupor, came the final, decisive blow. Smiley.
"Only through me))"
