I'm puzzled over the split between Yoona and Innisfree. What is the cause? Has there been an official explanation? Is there a connection between Yoona's karaoke outing with Lee Hyori on July 1 and this sudden announcement? Is Innisfree afraid of a possible public backlash from this incident? Or is there some other reason? Excerpt from an Allkpop news article (July 2): "Lee Hyori and YoonA were seen apologizing later through their Instagram posts. After seeing the apologies, the public was relieved and showed a positive reaction because the two stars were able to immediately recognize and apologize for their wrongdoings. A while back, there was a sudden surge of COVID19 infections caused by the karaoke mics in Korea. Another reason the public was more concerned over Hyori and YoonA even though visiting karaoke was not restricted."
