Ding Xiaomin (played by Guo Caijie) and her boyfriend Xu Hui (played by Xu Zhengxi) are both students of art. They traveled a long way to Paris, the capital of art, hoping to make some achievements there. In terms of emotions, the kind but somewhat stubborn Ding Xiaomin is devoted to Xu Hui. In order to fulfill her boyfriend's artistic dream, she is willing to give up her future and rely on working to subsidize her family to ease the tight economy. However, what Ding Xiaomin did not expect was that she was ruthlessly abandoned by Xu Hui. After a huge blow, Ding Xiaomin completely lost hope in men and love, and gave up on herself, living a muddle-headed and dark life all day long. One day, by mistake, Ding Xiaomin accidentally became the roommate of a man named Lin Junjie (played by Louis Koo), and Ding Xiaomin, who always thought that Lin Junjie liked the same sex, was taken care of by this kind man in every possible way.
