Fueled by the inspiration Jae-hee brought upon him, Tae-joon struggles to recover from his nearly lost career in high-jumping. With Jae-hee's constant support, Tae-joon's cold personality changes and he starts to develop feelings for her, despite negative reactions from his childhood friend, renowned gymnast Seol Han-na (Kim Ji-won), who anticipates having Tae-joon as her boyfriend. On the other hand, Eun-gyeol has rejected the love offered to him by his childhood friend Hong Da-hae (Nam Ji-hyun) and insists on affirming his love for Jae-hee. As they become closer to each other, Tae-joon reveals to Jae-hee about the death of his mother, which he blames on his father's indifference. The competition over who takes Jae-hee intensifies as her childhood friend and suitor John Kim arrives from America for a photo project in Korea. John Kim (Kim Woo-bin) attempts to talk Tae-joon down, but Jae-hee personally rejects his love.
Later, Han-na learns of Jae-hee's true identity after reading a secretly acquired yearbook of Jae-hee's previous school in America. Teacher Jang attempts to stop her from revealing the truth to no avail. The angered Han-na threatens Tae-joon to have her as a date before she kicks Jae-hee out of Genie High School. Tae-joon reluctantly consents, consequently receiving negative responses from the public. Later on, Han-na severely injures her ankle during a rehearsal and is feared incapable to do gymnastics anymore. She finally rejects Tae-joon, just as Eun-gyeol confesses his love for Jae-hee.
