Following a sudden, unforeseen accident that plunges him into a coma, Choi Joonwoong awakens to a bewildering realm populated by tireless figures resembling grim reapers, and an astonishing proposition unfolds before him.

Attempting to assist a television writer haunted by the reappearance of a former tormentor from her high school, Joonwoong struggles to adhere to Goo Ryeon’s instructions regarding emotional restraint.

Joonwoong’s official integration into Ryeon’s team coincided with an unexpected summons: a plea from his closest friend in desperate need of assistance. To answer that call, Joonwoong journeys into the past, where he witnesses the harsh rea…

Driven by a desire to persuade both father and son—across the expanse of time—to reconsider their choices, the team embarks on a delicate mission. Meanwhile, a spirit adrift recounts her tale to Joonwoong.

She remained tethered to the world, a spirit unwilling to depart until the weight of guilt lifted from her husband’s shoulders. While others of her kind pursued her, Ryeon’s team stood as a bulwark, holding the encroaching shadows at bay.

In the days leading up to his passing, a war veteran found himself unexpectedly revisiting the core of existence, sharing his story of a pilgrimage to Ryeon with Joonwoong and Im Ryoonggoo.

A new situation arises at a cosmetics firm. When their technology malfunctions, the team relies on keen observation to identify the likely source of the problem among the personnel.

The revelation of an online perpetrator facilitating suicides spurred Joonwoong to action. He could not stand idly by; he resolved to intervene directly.

A stark warning summoned the grim reapers to an unusual matter: a dog, lost from the companion he had known for years.

The woman haunted by the assault struggles with the enduring weight of trauma, while her twin brother pursues a relentless quest for justice. For Ryoonggoo, the case is deeply, irrevocably personal.

The malicious whisper about Ryoonggoo reached Joonwoong like a physical blow. It was a vile rumor, and its impact was compounded by the revelation of a far more terrible truth – the history that forged his colleague into the figure he now w…

A face known to the team resurfaces, though her disposition appears to shift unpredictably. Upon learning of this, Ryoonggoo intervenes.

A shared sorrow for a friend lost to time draws two women into connection. In their conversation, the story of the comfort women and the atrocities they endured is recounted.

The shadows of Ryeon’s history began to surface. Long ago, she had been a woman of noble birth, forever marked by a terrible ordeal that had left wounds both visible and unseen.

For Ryeon, the task of assisting a deeply troubled celebrity holds particular weight. Simultaneously, Park Joonggil presses for explanations regarding the concealed truths surrounding him.

Joonwoong sought out the individual who held the potential to avert Ryeon's descent. Their task remained unfinished.
