A woman wakes up in a hospital with no memory of who she is. She doesn't even recognize herself in the mirror. She hit her head while falling down the stairs and suffers from temporary amnesia. As she gets to know herself, she is disappointed to find out that her handsome husband doesn't even want to touch her and her career as an influencer is falling apart because she is suspected of murder. But it turns out she is living the life of her twin, Haemi.
