Freelance photographer Mara (Sarah Highland) has always adhered to the principle of having fun in time to meet scum men to break up quickly, and marriage is not part of her plan at all. Soon after getting along with her new boyfriend, she received an invitation to 15 weddings within a year, and the two decided to attend seven of them together, each with its own problems. Through their marriage, Mara also discovered her problems with her boyfriend, and the relationship between them began to become strained. At the same time, the boyfriend's family also began to urge them to get married and have children.
