On a rainy night, an uninvited guest broke into the home of Lin Xiaoxing, a 17-year-old high school sophomore girl - Lu Tingxiao, a warlord from the Republic of China. This "old antique" who was resurrected with unfinished obsessions is old-fashioned, arrogant, and "handsome". He knows nothing about modern life, but he protects his shortcomings and is loyal. In order to hide the secret, Lin Xiaoxing was forced to start the "Old Warlord Transformation Plan" to teach him how to use the toilet, play with mobile phones, and adapt to modern rules. In the chaotic life of cohabitation, the two gradually developed a bond from each other's mutual dissatisfaction.
