During an episode of Dream High 2 that was aired on the 21st of February, Leann (Ji Yeon) is attacked with a soccer ball and faints while performing on stage.

After Leann's mother took charge and demanded action from Lee Kang Cheul, Leann gets scheduled for a performance in a small festival in the countryside. Lee Kang Cheul tells Leann to go to ChungJu for the festival, so Leann take a bus and leaves for her performance.

Leann complains, "I'm going far into the countryside and you don't even get a car ready for me." When Leann arrives at the festival, Lee Kang Cheul texts her telling her to take a picture of herself in the stage outfit. And when Leann finds out what the outfit looks like, she completely freaks out. Her outfit consisted of cat ears and cat mask. On top of that, she had to perform "Bo Peep Bo Peep" on stage. The stage itself was small and pathetic.

Shin Hae Sung and JB were coincidently in CheongJu and showed up to the festival to support Hae Sung's little sister who was competing in a competition. When Leann realized they two were in the audience, she couldn't help but try to hide her face. Shin Hae Sung said, "It can't be Leann" and didn't recognize her at first.

She was almost done with her performance without getting noticed until a soccer ball suddenly attacks her. When the soccer ball hit her head, her mask flies off and reveals her face. Leann faints on stage and couldn't wake up for a while. Shin Hae Sung and JB were shocked and were hesitating on what to do when Jin YuJin (Jung Jin Woon) shows up and carries Leann off stage.
