In the eyes of friends, Celeste (Rushda Jones Rashida Jones) and Jesse (Andy Samberg Andy Samberg) are a perfect match. The love between the two continues from high school to this day, warm, lasting and full of passion. However, with the passage of time, in the eyes of the two men, the figure of each other is no longer as beautiful as it used to be, and Jesse's cynicism and unenterprising spirit are unbearable. Celeste's superiority and aggressiveness often hurt Jesse. In front of the two, there seems to be only one way to divorce. Although they cannot be husband and wife, the deep feelings between them still exist, so they decided to break up without separation, unable to make an agreement for husband and wife to be friends, and launched their new love life under the same roof. But the reality is not as beautiful as imagined, gradually, Celeste found that he is still deeply in love with Jesse, and the love is getting stronger and stronger. What made her feel even more painful was that Jesse, who once thought she knew very well, became more and more strange.
