다음 글에 드러난 주인공의 심경 변화로 가장 적절한 것을 고르시오. 

In the convoluted theatre of human existence, there are moments when the subject is caught within the tension between existential dread and the fleeting glimpses of solace. Such moments test the fragile psyche, oscillating between uncertainty and the eventual, albeit temporary, relief. Standing at the precipice of a new chapter in life, the protagonist found himself immobilized by an overwhelming sense of anticipation, his mind spiraling in the anxiety of the unknown. The bus, symbolic of his entrance into a new phase of professional life, became a metonym for the broader existential journey. Every passing second seemed to stretch into an eternity, as his consciousness fixated on the possibility of failure—of missing the opportunity that lay before him. His thoughts raced, fluctuating between the catastrophic and the hopeful, as time itself seemed to fracture under the weight of his anxiety.

But just as the tension reached its crescendo, a sudden intervention of fate—a bus arriving unexpectedly—shattered the temporal paralysis that had gripped him. In that instant, the crushing weight of existential dread dissolved, replaced by a profound exhalation of relief. The world, once again, seemed manageable, the future no longer a looming void but a path he could tread. He leaned back, allowing the brief reprieve to wash over him, though aware that such moments of tranquility were as ephemeral as the wind.
