This is a film that focuses on the ultimate emotional journey of Su Jinyue and Yun Zheng, who are "sad, sweet and full of pleasure" from tit-for-tat to deep-rooted love. The story breaks the gentle rhythm of traditional romance novels. In the sparks of mutual hostility, the pull of misunderstandings, the sadistic breakup and the ultimate confession, it not only shows the emotional game between modern men and women, but also hides the core of "reunion after breaking the mirror".
