Suddenly, the silence is shattered by a ringing phone. An unknown number from Korea. He frowns, his annoyance palpable. He doesn't make a habit of answering unknown numbers.

He ignores it, letting it ring out. But just a few seconds later, the same number calls back with persistence. His patience wears thin.

After the third ring, he answers, his voice a low, ice-cold growl.

"Speak."
