Ji Wanwan, Gao Yang's girlfriend of many years, a senior boy, suddenly left without saying goodbye and disappeared without a trace. Gao Yang was puzzled and fell into deep self-doubt. Later, by chance, he met Wu Zhenzhen, a girl who looked exactly like Wanwan in a bar. After contacting Gao Yang, he discovered that there was an unknown secret in Zhenzhen - when she was 13 years old, Zhenzhen was hurt, and the darkness, evil, pain, and sadness in her heart were extracted from herself, and she existed as another strange life form, the "hermit". After that, Zhen Zhen forgot the pain and was able to continue living. The two people fell in love with each other during the subsequent contact, but Gao Yang was still worried about Wanwan's departure, and Zhen Zhen did not make peace with her hurt past. Both of them fell into a deep swamp and were unable to move forward. Gao Yang wandered between the disappeared Wanwan and the cheerful Zhen Zhen, and finally embarked on a journey to find Wanwan, but fell into another bigger mystery.
Intention: Only by letting go of the past can you have a future.
