She was having a VERY “Good Day.”
IU is known as an “idol of idols,” and for good reason. For 17 years, she has blown away fans and fellow stars with her legendary vocals.

IU has an impressive vocal range, and her bright, clear voice is truly one of a kind. Recently, however, a bride went viral on Threads for sounding shockingly similar to the star.
On her wedding day, the bride, Anna Yuna, performed one of IU’s greatest hits for her guests, “Good Day”. The release of “Good Day,” the lead single for IU’s 2010 album Real, was a breakout hit that catapulted IU to stardom.
“Good Day” isn’t an easy song to cover, but Anna Yuna nailed every note, even IU’s jaw-dropping high notes that require expert-level breath control and power.
When the bride finished her performance, her guests cheered and chanted, “IU! IU!” She sounds like just like her! Anna Yuna is a musician, and she has 50.5k followers on Instagram, where she posts covers, photos from her daily life, and more.
