Netizens were surprised to see aespa spotted at BLACKPINK's concert in Seoul.

Fans were in for a surprise when members of aespa were spotted at BLACKPINK's concert in several fantaken photos. On September 17, BLACKPINK held the second day of their eagerly anticipated 'Born Pink' world tour at the Gocheok Sky Dome.

Based on the photos, all four members of aespa attended the concert. In the comments section, netizens expressed 'surprise' at this scene, as there hadn't been any substantial associations previously between these two groups.

On the other hand, there were also fans lauding aespa going out of their way to support their 'sunbae' group, even though they belong to different music labels.

Adding to the intrigue, netizens noted that aespa had just wrapped up their US tour before marking their presence at BLACKPINK's concert. It was evident that despite their grueling tour and long-haul flight back to Korea, the members of aespa showed their commitment and "amazing stamina."

Reactions include:

"I am just so happy to see the 4th gen girl group attending BLACKPINK's concert after touring and coming back to Korea. Thank you, aespa"
"I wish they would all take a selfie together at the end and upload it. Also, aespa has such good stamina...If I had gone on tour for over a month and been on the plane for 30 hours, then I probably would have K.O.ed..."
"I can't believe they just flew in in the morning. If they did, then their stamina is crazyyyy"
"I can't believe they attended after just wrapping up their tour...crazy healthy bodies"
"aespa even has an SM concert a few days later lol"
"I'm so happy that they attended"
"Were they invited or no? The seats look like they might not have been invited though"

"Haters just want to hate on the other company but honestly it just looks good for them to support each other"
"I wonder if their company sent them"
