Shin Ji Hyun was preparing for her wedding to Kang Min Ho when a terrible accident occurred, leaving her in a state of brain death, lost in a coma.

Within the borrowed form of Song Yi Kyung, Ji Hyun finds a certain delight. With this new vessel, she seeks employment at Han Kang’s restaurant.

The betrayal cut deep when Ji Hyun uncovered the clandestine affair between Min Ho and In Jung, a secret carefully concealed from her. This discovery was compounded by a further, more insidious revelation: Min Ho and In Jung were plotting …

Driven by a fierce determination to disrupt the plans of Min Ho and In Jung, Ji Hyun frantically searches for her seal. In her pursuit, she uncovers a hidden history between her closest friend and betrothed.

Heavy with a sense of dissatisfaction, the Scheduler takes Ji Hyun shopping, hoping to lift her spirits. Elsewhere, Min Ho finds himself increasingly drawn to Yi Kyung, a feeling he can't quite dismiss.

Han Kang consistently clashes with Yi Kyung, whose presence serves as a persistent echo of Ji Hyun, a deflection for emotions he struggles to acknowledge.

Assuming the guise of Yi Kyung, Ji Hyun enters Min Ho’s household as his new housemaid. However, her actions within that role begin to inflict harm upon the very person she has impersonated.

In Jung felt a disquiet settle within her at Yi Kyung’s presence in Min Ho’s house. Elsewhere, Han Kang found himself unable to shake the memory of Yi Kyung, even after dismissing her from his employ.

The prognosis for Ji Hyun’s father grew grim as his brain tumor advanced. In response, he finalized a new will, stipulating that his company be bequeathed to Min Ho.

Nearly half of her forty-nine days completed, Ji Hyun confronts the unsettling possibility that genuine affection eludes her entirely.

Driven by gratitude, Ji Hyun embarks on a quest to find the individual who wept for her. Meanwhile, Kang pursues a deeper understanding of Ji Hyun, or perhaps Yi Kyung, seeking to uncover the truth behind her identity.

As the days passed, Ji Hyun's influence over Yi Kyung grew subtly stronger, leaving her disoriented and adrift. A wistful longing stirred within Yi Kyung, prompting her to wander through recollections of the past.

A growing unease about Kang’s suspicion fuels Ji Hyun’s resolve. She feels compelled to resolve the matter concerning Min Ho before the symbolic end of her forty-nine days.

Ji Hyun discovered details of the Scheduler’s history, and the knowledge spurred a direct confrontation. The encounter seemed to shift his perspective on events.

Yi Kyung shared the details of her past with Dr. Noh, though they were not alone in the room. Meanwhile, Kang escorted Ji Hyun to the hospital to see her father.

Yi Soo relived the painful memories of his relationship with Yi Kyung. Meanwhile, Kang and Min Ho clashed over Ji Hyun, and Seo Woo finally confronted In Jung with the truth.

Kang and Ji Hyun both scrambled to prevent Yi Kyung from fleeing. Meanwhile, Min Ho attempted to exorcise a spirit inhabiting Ji Hyun.

Kang and Ji Hyun presented the seal to her mother, and then made an effort to speak with her father regarding Min Ho. Meanwhile, Yi Kyung also received gifts from Ji Hyun.

The third tear that traced a path down Ji Hyun's cheek finally stirred her from the long sleep.

Ji Hyun reflects on the events of the last forty-nine days, a period of extraordinary experience, and finds herself unexpectedly visited by Yi Soo. The question lingers: what brings him to her?
