Summary:
After watching a high jump competition on TV, Lu Rui Xi was deeply inspired by a jumper named Zuo Yi Quan. In fact, she's so inspired she decides to transfer to his school. However, Quan attends an all-boy school. So, she dressed up as a boy to get accepted. At the school, Rui Xi befriends Jin Xiu Yi. One day during their friendly soccer match, Rui Xi was knocked unconscious by Xiu Yi. Quan, who happens to be walking by, carries her to the infirmary. While carrying her, he realizes Rui Xi is actually a girl! However, Quan keeps her identity a secret, for he has slowly fallen in love with her.

This drama has got to be one of my all time favorites! I cannot wait for the second season cause the ending sucked.
