aespa's Karina was recently chosen as the advertising model for the vitamin C drink 'Vita 500 ZERO,' and has since boosted the brand's success to never-before-seen levels. Their recent ad featuring Karina reached over 11 million views.

However, the brand's new success has stirred up some controversy. Before Karina was selected as the model for 'Vita 500 ZERO,' the group Le Sserafim held that position. For their ads, Le Sserafim brought in around 3-5 million views. 

Some fans are now upset that the brand has switched advertising models from Le Sserafim to Karina, and the explosive success of Karina's recent ad has sparked debate among netizens:

"It's much brighter and better now"

"As soon as the advertising model changed, I bought Vita 500"

"Karina really suits this concept, she's so refreshing and nice"

"It seems like they just ran the promos differently...there's no point in fighting over who got the most views, and it's nothing to be proud of"

"Even if it's just an ad, it did get double the amount of views from before"

"They should have promoted Le Sserafim better..."

"For some reason, now it seems like the Bunnies fandom has started a fight between the aespa and Le Sserafim fandoms..."
