Description：The innocent and straightforward Dragon Girl (played by Fennie Yuen) tries to learn the method of making rain in the human world, and she must transform into a human. She originally wanted to travel around in the bustling human world, but she was deeply attracted to the philanthropic Ye Xi (played by Benny Chan), and the two began a "human-dragon love". However, "humans and dragons fall in love, they must be sent by heaven", which leads to a lot of problems and is out of control, but they still love each other. On the other hand, Zhou Chu (played by Chin Kar-lok), who grew up with Ye Xi, is a martial arts master but a strong character. He once believed that dragons were the source of all evil and was determined to take it as his responsibility to slay dragons. Once, when he went up the mountain to slay a dragon, he accidentally rescued the beautiful Princess Crescent (played by Cheung Shen-yuet), and soon began a close relationship. Unexpectedly, Princess Crescent also fell in love with Ye Xi, and a four-corner relationship began.
