"Choosing a Path in the Mirror" tells the story of Wan Wan, who after moving house, discovered that the old mirror in her bedroom could reflect the life she had not chosen. In the mirror, those "ifs" that have not been fulfilled become vivid: succeeding in the postgraduate entrance examination, falling in love with different people, and living in a distant place. When she began to rejoice at the moment, "she" in the mirror suddenly spoke and proposed to exchange their lives. The mirror surface is gradually becoming as warm as human skin. This is a suspenseful journey about choice, desire and true self.
