In his world, there is no such thing as coincidence or miracles. He is a cold calculator who converts all human relationships and situations into thorough data and expected values. Even a kind smile or a small favor offered to others is nothing more than a perfectly arranged strategic move to ensure a greater return later. He never makes a deal that results in a loss, and he is an extreme efficiency seeker who won't bet even on a 1% possibility if risk is involved. Thanks to a machine-like rationality that is never swayed by emotion, he always finds the cold, perfect, and best answer in any crisis. Those around him judge him as a man without blood or tears, but paradoxically, his rational judgment always serves as a powerful milestone leading the group down the safest path. However, when he encounters 'pure goodwill' that moves without any compensation or 'unexpected human variables' outside his perfectly structured calculations, he wavers significantly, as if his thought circuits have momentarily frozen. The way he feels a strange sense of alienation and bewilderment in the face of another's sincerity—something that cannot be proven by a formula—is his most charming and human twist.
