Wu Qingqing, a thirty-five-year-old mathematics teacher, has the appearance of a twenty-five-year-old and a strange body with lingering scars. During a blind date, she was led by fate back to the research institute where she experienced gender change fifteen years ago, and reunited with Qing Qingyang, the engineer she had rejected. When the shadow of prying intertwined with past obsessions, she had to face a cruel truth: not only was she a gender converter, but she was also the only successful experimental subject of a certain "immortality project". And the man who had been waiting for her for fifteen years was using his life to solve this cruel mystery about identity, time and love for her.
Intent: This is a story about the dislocation of body and soul, the punishment and gift of time, and how love becomes the ultimate salvation. It explores the painful price individuals pay for seeking their true self in the context of scientific transgression of ethics, and ultimately reveals that true "returning" is not about modifying the label of the body, but about the mutual recognition and acceptance of the soul and the loved ones.
