Rainbow's Woori talked about her hard work on 'Invincible Youth', for which she was a former cast member, on the 'Go Show'.

On joining the KBS 2TV 'Invincible Youth' cast, she stated, "I thought a lot about it myself [before joining]. There were lots of idols that were popular, but as for me, I only had one schedule per week."

She then related a story from one of the episodes stating, "We were told to make Im Ha Ryong sunbae laugh, and I thought about how I really wanted to win for a week. I kept thinking about what I could do to get first place. So I dressed up as a dragon. I colored band-aids black and stuck them on my eyebrows. Since I was a blue dragon, I colored my lips green and even held an orange with my mouth. It was an idea that I got after a lot of thinking."

"I wanted to be funny so I lied down on the floor, but the floor was so cold because it was winter," she continued. "I thought to myself then, 'Do I have to do things like this?'. In the end, I won 1st. The staff complimented me a lot as well. It really hurt to take the band-aids off."

Woori shed tears as she thought back on the various things she tried to do to gain more attention for herself as well as the rest of her group in the past, touching the hearts of the audience and the MCs. Woori also discussed the struggles she and her group have faced on the same episode.
