Liu Yiyang (Zhang Wen) and Tong Jiaqian (Yao Di) are a couple who have known each other for nearly ten years. Unlike Jiaqian's well-off family, Yiyang was born in a working-class family. Not only can he not offer a car and diamond ring to his fiancee, but he also has no love inn for the two of them. He still lives with his parents and grandmother, which has become the main reason why Jiaqian's parents oppose their love. However, this young couple, under the banner of love first, openly joined the fashion trend of naked marriage. But love can't be eaten after all, especially marriage is a matter of two families. Life after marriage has become more and more realistic, and various discomforts and conflicts have also appeared one after another. How should Yiyang and Jiaqian face these troubles? This film is adapted from Tang Xintian's (net name Xiao Guier'er) popular online novel "Naked Marriage - The New Marriage Era of Post-80s".
