CEO Jang Seon-gyeol, a man of exacting standards, found himself unexpectedly encountering Gil O-sol, a job applicant with a decidedly more relaxed approach to order, while searching for his errant robotic vacuum.

Growing increasingly desperate, she resolved to apply to one more position—a place where her talents might prove useful.

She had a new job, and he found her there. Later, he discovered her intoxicated on the street. Reluctantly, he offered her a ride home, a decision he would soon regret.

He awoke in the sterile quiet of a hospital room, utterly disoriented. The how of his arrival was lost to him, a blank space in his memory. O-sol attempted to soothe his confusion, while simultaneously, her transformed appearance drew aston…

O-sol was taken aback by the revelation of Seon-gyeol's affliction.

Seon-gyeol felt a tightening in his chest, a sharp ache mirroring the news he'd received: O-sol's new assignment. He couldn't reach her, and the distance fueled a growing unease. Meanwhile, O-sol was left disoriented by Seon-gyeol’s sudden…

A quiet intensity settled over the room. Seon-gyeol, lost in thought, unexpectedly confided in a neighbor, pouring out his heart. Meanwhile, elsewhere, a subtle shift occurred – a realization dawning amidst the demands of work. The moment o…

She was caught in a difficult situation, and O-sol offered assistance. Her words lingered, a persistent echo in her thoughts.

She returned to her work, the implications of the situation settling within her. When a client makes a false accusation against her, Seon-gyeol fiercely defends herself, jeopardizing the company in the process.

A disquiet settled upon him, a bewildered curiosity at finding O-sol in his own space. The situation grew more complicated with the unexpected arrival of his mother, and from that moment forward, a subtle shift occurred – in the atmosphere …

A subtle tension hung in the air. Seon-gyeol seemed perpetually watchful, his attention keenly focused on everything around him. This attentiveness, however, sparked a disquiet within others. A sense of unease bloomed, a feeling that someth…

She made it clear she wasn't seeking a romantic connection, yet he orchestrated a spontaneous gesture, revealing a facet of his personality she hadn't yet seen. He persisted in a way that challenged her initial assumptions, hinting at depth…

She had always been attuned to his eccentricities, finding a strange sort of empathy in his quirks. Yet, after a long period of considering her feelings, she made the difficult decision to leave.

Resolved to conquer his fear, O-sol sought a cure for his mysophobia. However, when his family unearthed a hidden truth about his grandfather's past, she reached a stark and irreversible conclusion.

The revelation from his grandfather struck Seon-gyeol with the force of a betrayal – a profound sense of being deceived by someone he had always implicitly trusted.

A departure looms: Seon-gyeol is leaving for the United States. With his impending exit, a long-overdue apology finds its way to O-sol's family. He seeks a fresh beginning, yet the possibility remains that it is already beyond reach.
