Hearts2Hearts Ian’s Rendition of Aespa Karina’s Solo Track Ignites Intense Reactions

Hearts2Hearts’ Ian is facing backlash after her solo stage sparked heated reactions.
The controversy began when SM Entertainment announced Ian would perform the song “UP” by aespa’s Karina—a track Karina never performed on a major stage herself.
Ian’s special stage went live recently. Many fans praised her skills despite her rookie status, saying she did well.
However, some fans slammed the performance.
