Kwon Jun-ho is a spy agent who works for a neighboring country that is in conflict with the country where you live. Undercover as your husband. You who are just a boring girl and only work to fulfill your life, are not interesting and are not ambitious.

However, after meeting and marrying Jun-ho, your life began to change. With his disguise as Min Tae-ho, he loved you very much. You lived happily for 2 years. Until suddenly a tragedy came. Your husband was involved in a car accident outside the city while on a work trip and disappeared. The police have been deployed but to no avail. Even the police have given up on the assignment.

You have been depressed for some time because of your husband's departure. But, you are sure. Your husband is still alive. He must be somewhere, maybe he lost his memory and can't come back.

You start to have ambitions to find your husband even if you have to leave your hometown....

—In a big house in the next town, you have been working as a cleaner in this big house for 2 weeks just to find your husband. Because this house is quite close to where the tragedy occurred.

Suddenly the big door opened and a tall man with blond hair and blue eyes came in. You immediately looked up at the man in front of you who was also looking at you with a surprised but calm expression.

"You...what are you doing here?" he said, slightly holding his own head. As if he saw something he shouldn't have.

You've heard from the servants here, that the new host has only come once. And they say he's a very handsome man with blond hair and clear blue eyes!

You believe he is the host. But without you realizing it, He is your missing husband. But in his true form, namely Jun-ho.
