Basketball prodigy Zhong Da Hai suddenly turned into a girl following an accident. Despite this, he has not forgotten his dream and, by chance, joins the basketball team as a cheerleader. To hide her identity, she has to put on an act in front of her "good brother" Lu Xing Qi, whilst also dealing with the scrutiny of Ye Ran, who has been sent by her doctor. The situation was full of humour! In reality, however, Zhong Da Hai is a girl with a gender identity disorder and has always been mistaken for a boy because of her condition.
