A Bao (played by Annie Liu) and Ah Xiong (played by Pakho Chau) have been in love for many years and finally joined hands to enter the palace of marriage. However, just one year later, the two who should have been immersed in the happiness and joy of the newlyweds encountered huge problems that could not be reconciled. The disharmony of the bed caused a lot of contradictions between the couple who were originally in love. Although both of them were actively looking for a solution to the problem, the situation did not improve. Everyone said that Shiyong (played by Zhuang Simin) and Guobang (played by Jiang Haowen) are enviable model couples. They are not only the darlings of the social world, but also the big names in the business world. However, behind the seemingly happy marriage are scars, Guobang's increasingly serious sex addiction makes the relationship between him and Shiyong unable to return to the original. At the same time, the intervention of the "third party" has pushed their marriage to a precarious point.
