In the modern apocalypse, Li Wanzhao, a female electronics factory worker, rescues former bartender Gu Zhaoming while escaping - a rational vampire who is afraid of the sun and pain and does not even dare to suck blood. The two were forced to survive together. The heroine used factory skills to create a "vampire survival suit" (sun umbrella with iron sheet, garlic necklace, tomato juice supply), while the hero used his bartending skills to coax the heroine to eat and help her cover up. In the process, they encountered a former boss who had become a blood slave, a cruel pure-blood vampire leader, and various funny scenes (the male protagonist cried because of the garlic, the female protagonist used a wrench to block the sun for the male protagonist, and the male protagonist was electrocuted until his hair exploded when the two men repaired the generator). In the end, the heroine finds her missing brother, and the hero also discovers "a way to live without sucking blood" - the heroine's "human smoke" is his "antidote."
