24-year-old Chen Meiru (played by Bu Guanjin) is an Internet information inspector with a eccentric personality. On her birthday, her only best friend Jiang Huizhen (played by Zhu Yanmanzi) arranged a birthday party for her. That night, she was entangled by a man dressed as an ancient Babylonian - he called himself a prince (played by Feng Shaofeng) and was born to love her. Chen Meiru thought it was a prank until the "prince" said his name... Chen Meiru was struck by lightning and was forced to retrieve her unbearable girlhood memories - the handsome and extraordinary mixed-blood prince who loved her alone, the beautiful and powerful rival princess (played by Xu Weining), the prince's best friend, the top tycoon (played by Wang Ruichang), all of which were characters she made up in her diary when she was 12 years old. The plot in the diary is bloody and childish, and now these three people have appeared in her life as a group. Could it be that... these "diary people" have become spirits?
