In Shanghai, a grand wedding is about to be held in a rather ordinary-looking apartment building. Despite careful preparations, all sorts of unexpected mishaps send the wedding in an unpredictable direction. Afterward, the apartment is officially renamed Love Apartment, and, quite naturally, welcomes seven young men and women from all walks of life, each with a different job and personality: Lin Wanyu, Chen Meijia, Lu Zhanbo, Lu Ziqiao, Guangu Shenye, Hu Yifei, and Zeng Xiaoxian. In the days that follow, these members of a new generation fall in love, quarrel, and trade jokes, passing one noisy yet unforgettable day after another. Romance begins to blossom in their hearts, too.
