T-Ara member JiYeon, showed off some of her Taekwondo skills on the episode of Dream high 2 that was aired on the 6th.

In the episode of Dream High 2, Kang SoRa and JiYeon's incident occured as a result of an argument they were having. They were getting on each other's nerves when they had to share a dorm room at school.

JiYeon states "I think what you need to do is not dream, but give up!" (Regarding Kang SoRa's career aspirations)

Kang SoRa, furious, pulls JiYeon's hair that infuriates JiYeon even more... as a result, JiYeon does a spinkick, leaving Kang Sora's nose bleeding.

JiYeon has previously revealed that she learned Taekwondo since she was 5 years old and holds a 3rd degree black belt, which is probably what made the scene seem more realistic and entertaining
