Has fans surpassed the levels of official pop-up stores?

On an online forum, netizens talked about a birthday exhibition and merchandise ('goods') prepared and organized by fans for aespa's Karina. With her birthday falling on April 11, fans opened up an exhibit on April 9 with adorable decorations, props, posters, and cake.

The fans also sold unofficial merchandise designed on their own, ranging from milk glasses to stamps and character dolls. They also prepared roulettes and other games that visiting fans can play. A panorama made by Karina's fans as part of the exhibit also showcased an artwork made from her solo stage at their recent concert.

This exhibition became so popular for its quality that the line to enter the event extended far across the side of the building. According to the original poster, the quality of this exhibition 'surpasses that of her company's official pop-up store.'

Reactions include:

"This quality is just daebak..."
