On the summer night of Shanghai in 2015, Zong Ying, a forensic expert, bumped into an unexpected visitor named Sheng Qing Rang at home. He said that he was also the owner of the apartment No. 699. He came to modern times every night from 1937, and then went back to his era in the early morning. Zong Ying, who has always been rational, thought it was nonsense, but when Sheng Qing Rang disappeared in front of her, she had to begin to accept this fact. From the accident at the beginning to the initiative later, with Zong Ying and Sheng Qing Rang going back and forth between two eras, the two people with emotional restraint gradually changed from friends to confidants and finally lovers in the storm of self and family, peace and war. However, with the outbreak of the Battle of Shanghai, Sheng Qing Rang's future is overshadowed by death, and staying together has become an unattainable luxury. Zong Ying was not afraid of life and death, and was determined to face the doomed history with Sheng Qing Rang. In the flames of war, two people who do not belong to the same time and space become the most important footnotes in each other's lives. "Night Wanderer" is a fantasy love drama that travels through time and space, based on the novel with the same name by author Zhao Xizhi.

I shouldn't have been walking around alone at night. I shouldn't have stopped and watch the obviously crazy man set the building on fire. And I sure of hell shouldn't have accidentally caught his attention. Then maybe, just maybe I wouldn't have been kidnapped by the world's most evil super villain. And then hopefully right now I wouldn't be wishing that he wasn't completely crazy, and wanted to kill every super hero in the world, and that he would, I don't know, take me to the movies, hold my hand as we walked together, or maybe take me to dinner one night. You know normal, cute couple stuff. Instead he likes to kick puppies when no ones watching, dropping me from high buildings, and throwing people into traffic, annoyingly. Maybe if I had just minded my own business and kept walking, maybe I wouldn't have been taken by someone who's whole mission in life is to watch every super die, and cackle evilly while he thinks of it. Maybe if I had just minded my own business and kept walking, maybe I wouldn't start feeling bad for this super villain. Maybe I wouldn't be questioning everything I've ever learned about him. And God forbid, I wouldn't be loving a villain.
