Ma Xiaoqiang (played by Li Cansen) is a playboy who hangs out with friends all day and lingers in the entertainment field. By chance, he met a girl named Pingguo (played by Li Shanshan) in a nightclub. The two fell in love at first sight and had a hot fight that night. The next day, Ma Xiaoqiang learned that Pingguo's father was actually the underworld boss Jiu Wenlong (played by Chen Huimin). Pingguo took Ma Xiaoqiang to meet his father. Jiu Wenlong asked Ma Xiaoqiang to guarantee his life and would not let his daughter down. Although Ma Xiaoqiang's heart had retreated, due to the power of Jiu Wenlong, he had to suppress his inner turmoil and honestly dated Pingguo. But at this juncture, a Japanese flight attendant named Yu Li (played by Kasugai Shizuna) moved to Ma Xiaoqiang's next door. She was sexy and beautiful and threw herself into Ma Xiaoqiang's arms every day.
