Ha-yun, who was struggling on his own, rescued a Persian cat who got almost hit by a car.

It was a good deed without any special intention, but the cat brought a long-haired woman lying naked in front of his house as if she were boeun.

Ha-yun misunderstood her as a fan and tried to kick her out. However, she insisted that she was the guardian angel and persisted to stay around Ha-yun.

She speaks and acts very differently than ordinary people.

When the situation is twisted, Ha-yun is forced to hire her as a manager and live together. Blue, the cat that brought her along.

But the more he looks at this woman, the more difficult it becomes. Is she really... an angel?
