Su Nian and Gu Jingchen agreed to marry for three years. She is a tool who married into a wealthy family, and he is a cold and taciturn CEO. In three years, the two went from being strangers to getting used to each other - until a car accident wiped out Gu Jingchen's memory of three years.
When he woke up, he didn't remember that he was married, and his white moonlight happened to return.
Su Nian must make this husband who has forgotten her fall in love with her again within three months, and she is also hiding another secret - she is pregnant.
