On October 27, ILLIT’s official social media account released a short challenge video with the caption “#You’reUnderArrest with IU.”
In the video, IU joins Wonhee for the challenge to ILLIT’s new song “You’re Under Arrest.” IU showcases a relaxed yet stylish look, pairing her long, straight hair with a light blue striped uniform, loose-fitting pants, and blue-toned sneakers.
In particular, IU effortlessly performs the song’s signature choreography, including blowing a whistle and forming a gun shape with her hand. Her relaxed movements and expressive facial acting highlight her distinctive charm even in the short clip.
What particularly caught viewers’ attention was the two stars standing side by side.
IU, who was born in 1993, and Wonhee, who was born in 2007, have a 14-year age gap. Despite this, they share a similar vibe and adorable visuals. At the end of the video, they made heart shapes with their hands together, creating heartwarming chemistry between the senior and junior artists.
Wonhee, the other star of the challenge, also expressed her excitement about meeting IU. On October 28, she took to the fan communication platform Weverse and wrote, “I filmed a challenge with IU sunbaenimㅠㅠ,” expressing her overwhelming joy.

Wonhee, who is known to be a fan of IU, could hardly contain her excitement. “She’s really cute and pretty, and I even got my Palette album, which is one of my favorite albums, signed. It really felt like a dream,” she said. Filming a challenge with an admired senior and getting an autograph on an album she treasures made the encounter an especially memorable experience.
The video was also uploaded to ILLIT’s official YouTube channel.
As of 4 p.m. on October 28, the clip had surpassed 1.4 million views approximately 18 hours after its release. The video has drawn particular attention because IU, who does not frequently participate in dance challenges, joined in to help promote ILLIT’s new song.
Netizens who saw the two stars together shared enthusiastic reactions to their visual chemistry. Comments included, “I keep looking at IU and then Wonhee, and the video never ends. What a blessing to see such beauties,” “IU really looks so young,” “Their faces give off sister vibes,” “They have a similar visual style, so they look adorable together,” “I can’t believe I’m seeing IU and Wonhee together,” “I never thought they looked alike before, but now I see it,” and “I want to be arrested.”
Meanwhile, IU continues to pursue an active career as both a singer and an actress, while ILLIT is connecting with fans through its new song “You’re Under Arrest.”
