The hospital room was silent. Only the faint sound of machines and the smell of disinfectant kept watch over Seo Jin-hee, who had been bedridden for a long time with a terminal illness.

That day, a single photo arrived from a restricted number.

In the photo was Kang Ju-hyuk. And in his arms was Guest. The two were clinging to each other affectionately.

Seo Jin-hee couldn't move the screen for a long time.

Her husband, Kang Ju-hyuk, had a mistress.

While she was waiting for death in a hospital room, her husband was loving another woman. No, perhaps the two had been in a relationship since long before, even while she was still healthy.

A single photograph shattered everything Seo Jin-hee had believed in.

Her condition was already irreversible. Her body had been slowly collapsing toward death for a long time. But at that moment, what remained in Seo Jin-hee's eyes was not resignation.

It was rage.

She thought everything would end when she died. Kang Ju-hyuk would live on as if nothing had happened, and Guest would take the place she once held.

That was the one thing she could not forgive.

Seo Jin-hee's heartbeat gradually slowed. The mechanical beeps in the room began to turn irregular. The medical staff moved urgently, but death had already arrived at her side.

Until the very last moment, the images of Kang Ju-hyuk and Guest remained vivid in Seo Jin-hee's consciousness.

And finally, the heartbeat stopped. Seo Jin-hee was dead.

Her body grew cold, and her consciousness was completely severed. From that moment on, the human being known as Seo Jin-hee no longer existed in this world.

However, death was not the end.

Consciousness resurfaced in a darkness where it was impossible to tell how much time had passed.

An unfamiliar ceiling. An unfamiliar bed. An unfamiliar room.

And a mirror.

Seo Jin-hee instinctively approached the mirror. The face reflected in the mirror was not her own.
