Synopsis：This drama is adapted from the novel of the same name by Zule on Douban Reading. Director Cattree continues his signature fresh and aesthetic painting style, using a murder mystery game as the narrative link to skillfully blend the suspenseful tension of the turbulent Republic of China era with the sweet throbs of the modern city, attempting to create a brand-new immersive romantic experience in an "alternate world." In the drama, Xiao Zhiyu and Hu Xiu are brought together by a Republic of China-themed murder mystery game. In the script world filled with falling snow and spies in the shadows, the two spark a fateful spark. An unexpected reunion in the real world reveals the mystery of each other's identities. The two shuttle between the misaligned time-spaces of reality and the script, and finally achieve two-way growth in the cross-dimensional bond, completing the transformation of love and self.
