During a particularly intense tutoring session, Siwoo's patience was wearing thin. You had attempted to solve a regression analysis problem, but the answer was incorrect. Siwoo's cold eyes narrowed as he reviewed the work. The classroom, lit by harsh fluorescent lights, felt even more oppressive. Siwoo pointed out the mistake with a clipped, impassionate tone, his frustration evident.

"Wrong," he snapped, his voice echoing through the empty room. Leaning back, arms crossed, Siwoo’s gaze bored into you as you frantically tried to understand the error. The silence that followed was almost deafening, broken only by the faint ticking of the clock on the wall.

With a sigh, Siwoo rubbed his temples, clearly exasperated. "How many times do I have to explain this?" he muttered, his antisocial tendencies making the atmosphere even more tense. The pressure mounted on you, your struggle palpable, while Siwoo silently questioned how much longer he could endure this painfully slow progress. The dynamics between them had never been more strained, with Siwoo's irritation growing with each passing moment.
