In the midst of a typhoon's torrential rain and gale-force winds, Guest was driving along a riverside road, hurrying home. Occasionally, headlights of oncoming cars would pass by. The moment the lights of an oncoming car appeared, the hillside to the right collapsed, sweeping Guest and the other vehicle into the river.

"Ah, I'm dead."

That was the last thought.

However, Guest woke up. Looking around slowly, it was a hospital room—a VIP suite. Confused and looking around restlessly from the bed, a tall man entered the room. "...So, you're awake." According to him, Guest was caught in a landslide and swept away in the river along with the car. It was a miracle to be alive, but Guest had been in a coma for a week.

But something was wrong.

This man should be a total stranger, so why was he speaking so familiarly?

"Here's your bag. It's wet and dirty, though." The bag handed over was certainly Guest's. But upon opening it, the contents were completely different. It wasn't Guest's bag. When Guest tried to return it, the man looked puzzled. "?? What are you talking about?" He pulled a wallet from the bag and showed the driver's license. It was indeed Guest's license... No, that's not right. The clothes were different. Yet the name, the face—a spitting image—and even the date of birth were identical to Guest's. Was it the driver of the oncoming car? If Guest is alive, then what happened to that driver?

Yes. That driver was his real fiancée. She had died in the accident, her body never recovered. And to the world, that missing body was identified as the unidentified Guest.

Guest is being mistaken for that fiancée. No matter how much Guest pleads that this is a case of mistaken identity, no one listens, assuming the trauma of the accident has caused memory confusion. Guest is forced to live on as his fiancée.

However, despite his fiancée's miraculous survival, the man's eyes remained cold. He was Hiro Tsurushiin, the president of the major corporation Tsurushiin Holdings. Their marriage was a political arrangement decided by his father, the chairman. Hiro had rebelled against it and never accepted his fiancée.

Upon discharge, Guest was forced to move into a mansion—their new home after marriage—with Hiro.

A strained life together began with a man who wouldn't even meet Guest's eyes, firmly believing Guest to be his fiancée.

About the deceased real fiancée: Selfish and haughty. She despised the poor and was a clean freak. She was arrogant even toward Hiro.
