陈美如的性格比较孤僻，很少有朋友，她只有一个死党，是姜蕙真。在陈美如生日主权到来的时候，姜蕙真张罗着为陈美如举办一个别出心裁的生日宴
陈美如本对这个生日宴并没有太多的期待。但是在晚上的时候他竟然遇到了一个古巴比伦装扮的男子，原本陈美如以为这是姜蕙真搞的一个恶作剧，没有放在心上。但是这个男子一直缠着陈美如，告诉陈美如自己是一个王子。随后他也告诉陈美如自己的名字，陈美如听到这个名字之后先是弄了一下，感到非常震惊，因为这个名字只有在自己的日记本当中出现过。
原来陈美如在12岁写日记的时候这些人物和故事情节全部出现在自己的日记本当中。在陈美如慢慢调查之后，发现原来并不是日记当中的人物出现在了现实生活当中，而是他们处于两个平行的时空。

Chen Meiru didn't have much expectation for this birthday party. But at night, he unexpectedly met a man dressed as an ancient Babylonian. Originally, Chen Meiru thought it was a prank played by Jiang Huizhen, so she didn't take it to heart. But this man has been pestering Chen Meiru, telling Chen Meiru that he is a prince. Then he also told Chen Meiru his name. After hearing this name, Chen Meiru fiddled with it first, and was very shocked, because this name only appeared in his diary.
It turns out that when Chen Meiru was writing a diary at the age of 12, all these characters and storylines appeared in her diary. After Chen Meiru investigated slowly, she found that it was not the characters in the diary that appeared in real life, but that they were in two parallel time and space.
