IU tried to hide her short hair, but she ended up getting caught by her fans.

It is amusing to hear that IU tried to keep her transformation to a bob haircut for the first time in 10 years a secret until the music video was released. She prepared for a surprise reveal by concealing it with hair extensions, but it seems she couldn't escape the fans' keen eyes. This shows just how much interest and affection fans have for her, never missing even the smallest change, and the bob style is garnering significant attention as soon as it was revealed. I look forward even more to IU's future activities with this new look.
