In the latest clip uploaded on IVE's official YouTube channel, IVE drew attention to the members' reactions after seeing flip phone and slider phone. As a response, millennials conveyed how they suddenly feel old, emphasizing the huge generation gap between new idols.

On the 28th, a behind-the-scenes video was posted on IVE's official YouTube channel. The video showed the six-member group filming content for 1theK Originals, "Our Beloved."

In particular, the video is comprised of IVE's vocal cover of the songs K-pop enthusiasts and listeners loved through the years, from 2002.

14-Year-Old Leeseo Stunned After Seeing a Flip Phone

In the bts clip, Jang Wonyoung, Gaeul, and Leeseo started covering Girls' Generation's "Into the New World."

The filming set followed a concept inside a shaved ice café which was popular in the 2000s, around the time the song was dropped. To give a nostalgic feeling, the studio was also filled with old items including a flip phone.

As the video went on, Leeseo, who was born in 2007, especially attracted attention as she was amazed by the flip phone and asked Wonyoung, "What is this?"

However, Jang Wonyoung who was only born in 2004 seems to know what it is but eventually shrugged her head and replied, "I don't know."

Other members made viewers feel the huge generation gap as well after Rei struggled to open a slider phone.

When the production team taught her how to open it by sliding it, Rei was surprised, saying, "It's awesome!"

She then recalled, "When I was young, I remember decorating my folding phone because there were many cute emoticons." The Japanese-born idol expressed that she knows what a flip phone is, which is also popular in Japan back then.

After learning how to open the slider, Rei turned to her co-04 line idol Wonyoung and taught her how to use it. Jang was also surprised at how to open a different cell phone and said, "My mom used this."

Millennials React to IVE Who Were Amazed by Slider and Flip Phones

Immediately after the video was uploaded, Millennials or Generation Y who were born from 1981 to 1996 drew laughter after conveying how they suddenly felt the huge gen gap.

"Grandma is crying," "I can't believe I've become a mother's generation among children these days," "IVE making me feel ancient," "I played with these during my childhood," and more.

Some Generation Z internet users who were born from 1997 to 2000, also expressed their reactions and said, "I'm only four years older but why do I feel so old?," "Smartphone users won't understand the anxiety of flipping and sliding these phones," and more.
