"You see clearly, I am not her." When Lin Xiaoya heard her boyfriend Xu Chuan call the wrong name for the third time during an intimate moment, she finally could not ignore the ghost hanging in their relationship. She looks similar to Xu Chuan's late lover Lin Yuqing, but has a completely different soul. In order to understand this twisted love, she began to imitate everything about Yuqing - from clothes, hairstyle to living habits. When the image of herself in the mirror becomes more and more unfamiliar, and snowflakes fall again in the Beijing night sky, she understands that she must make a choice: continue to be a perfect substitute, or find her true self. This is not only a story about wrong love, but also a journey of redemption to find yourself.
