Entrepreneurs Wei Da Bao and Yu Xiao Tao work together to open an advertisement company. However, because of pressure of rent, they decide to search for co-renters. They meet a straightforward online jockey who is passionate toward acting, a female detective who is upright and serious, and the humorous son of a wealthy tycoon who wants to prove himself. The appearance of a seller who just graduated from university and seeks to open her own business opens a new chapter in Wei Da Bao and Yu Xiao Tang's life. They do not have a strong background, nor wide connections, but they seek to achieve their goals with their hard work.
