As the series opens, Kang Tae Joon wins a gold medal and sets a world record as he leaps to victory during the high jump finals of the 2010 Youth Olympics. Gu Jae Hee cuts her hair and arrives at Genie High under the guise of a male transfer student.
Tae-Joon faces scrutiny as his father, Director Jang, and a nosy reporter become suspicious that he may be faking his injury. After Doc discovers that Jae-Hee is a woman and threatens to have her expelled, she reveals that the real motivation behind her deception is to help Tae-Joon high jump again.
