In the eyes of the public, Tom (Jason Segel) and Violet (Emily Blunt) are a match made in heaven. After a year of love, they both think they know each other best in the world, and they get engaged in a flash. Violet longs for a perfect family, but also hopes to have her own career. She received a dream position at the University of Michigan, but the premise is that Tom must give up his current job and move to Michigan together. Tom agreed, but life in Michigan is not as good as he thought. On the one hand, he can only find a job in a snack bar with strong professional skills to make a living. On the other hand, Violet has repeatedly achieved success in the workplace, and the distance between the two is getting farther and farther. The contradictions intensified with Violet's step-by-step promotion, and the wedding of the two was postponed year after year. Just when the two of them made up their minds to hold the wedding, a kiss from a third party created an unhealable scar on their relationship.
