One observant netizen recently brought attention to IU's latest Instagram story post. 

On February 16, IU shared a YouTube link, showcasing a cover of her hit track, "Love Wins All." What caught this netizen's eye was the surprising revelation that the YouTube channel actually belonged to actor Jo Jung Suk.

The netizen explained, "This YouTube channel had less than 1000 subscribers. How did IU know about it that she posted the cover by an ordinary person? (Maybe Jo Jung Suk asked her?)."

The YouTube channel @cgs-records uploaded covers performed by an anonymous person, including an 'AI' cover.

Fans quickly picked up on subtle clues that the YouTube channel belonged to Jo Jung Suk. Especially the distinct guitar design in the video and the familiar voice accompanying the cover of IU's track. 

The netizen who created the post shared, "That guitar is the exact same one that Jo Jung Suk's fans sent him as a gift so people are certain it is him."

What adds to the intrigue is the mix of content on the channel. It began with an "AI version of Jo Jung Suk" covering Gummy's "Please Forget Me," and now, the latest addition is a cover of IU's song.

The netizen shared that fans who recognized Jo Jung Suk's voice left hilarious comments on his "AI cover" of his wife's song. Fans left comments such as "Hey, you can act like AI too," "I'm sorry what kind of AI can add ad-libs? lol," and "What kind of AI marries Gummy?" 

Other netizens commented, "It's so hilarious he acted like AI lol. So cute," "I live in Jo Jung Suk's neighborhood and see him at marketplaces sometimes. That mint sweater is Jo Jung Suk's. It's so Jo Jung Suk. He was food shopping wearing that once," "Jo Jung Suk is IU's acquaintance and I think IU posted the video because it was hilarious. I think Gummy also was posting comments on his videos, lol," "His voice sounds just like Jo Jung Suk lol," "It's so hilarious how he pretended to be AI in his first video," "I was wondering what this post was about, lol," and "I love Jo Jung Suk. It's so hilarious how he got his YouTube channel found out."
