Description：Happy Ghost (played by Wong Pak Ming) was reincarnated and transformed into a teacher in a girls' middle school. In his class, several naughty girls who love to play tricks on others, Dai Zhuoyi (played by Fennie Yuen), May (played by May Lo) and Yao Qiong (played by Ka Ling Chan), set up a "despicable club" to play tricks on others. Happy Ghost is their favorite target of jokes. Happy Ghost likes a female teacher in the boys' school next door. Just as he is about to launch an offensive, he finds that the teacher is being pursued by a physical education teacher who is better than him in all aspects. Compared with his ugly appearance, Happy Ghost is depressed. What is more devastating is that he fell into the "trap" set by Dai Zhuoyi and his group, and was misunderstood by the principal and forced to leave the school. Dai Zhuoyi and his group regretted it and began to find ways to make up for their mistakes.
