“Single’s Inferno” With A-List Idols? — Sexy Video Featuring Top Boy Group And Girl Group Members Stirs Up The Heat

One of the arbitrary restrictions in the K-Pop industry, even today, is the prohibition on free mingling between male and female idols. Though in recent times, many male-female idol friendships have been able to break through this boundary, hints of romance or anything similar are still very much a stigma. So, when netizens saw a top boy group and a top girl group acting in a sexy commercial together, it was nothing short of uncanny valley.

The groups in question are 2PM and Girls’ Generation, two of the most top tier idol groups from second-generation K-pop.

Back when the two groups were riding the peak of their popularity, the members frequently collaborated for variety shows, MC-ing, advertisements, and year-end stages. One of their most iconic collaborations was the “Cabi Song,” a promotional single by the two groups. Released on May 20, 2010, it was a promotional song for the Caribbean Bay water park at Everland Resort.

The song came with a full-fledged music video featuring Girls’ Generation members YoonA, Seohyun, and Yuri, along with 2PM members Taecyeon, Nickhun, and Chansung. Shockingly, it featured some not-so-PG scenes, including Nickhun rubbing sunscreen on Yuri’s back and YoonA almost grinding on Taecyeon!

The video recently resurfaced after a netizen compared it to the Netflix dating show, Single’s Inferno.

Others got nostalgic over the clip, reminiscing about how different idol culture was a decade ago.

• “Wow, that’s something you couldn’t even imagine happening nowadays, lol.”
• “Aside from those commercials, there was actually a show where they gathered people for a real dating reality program, too. LOL.”
• “It’s literally Single’s Inferno Was Too Hot to Handle even out back then? I wonder what the reference was, LOL.”

• “I f*cking hated it, seriously. I was thinking, ‘My unnies are doing *this*?’ Now I look back and laugh about it though…”
• “Back then, idol culture wasn’t something enjoyed solely by fandoms; it was consumed by the general public—or rather, driven by them—so the prevailing attitude was simply, ‘If the public likes it, that’s all that matters.'”
• “That was huge back then, seriously.”
