IU has been followed by the title 'nation's little sister' ever since her rise to stardom, but she revealed that she rather not be called by that.

On the March 14th broadcast of SBS Radio 'K.Will's Young Street', she asked about the nickname, and IU shared, "The first generation of the 'nation's little sister' is Lim Ye Jin sunbaenim and below her, everyone is equal."

IU continued, "I just want to be a nation's citizen... There are a lot of celebrities who are holding the title of the 'nation's little sister' these days, so I don't think it holds much meaning."

She also revealed how she became friends with Kim Yuna, "We once did a variety show together and sang a duet song, so I became friends with her," sharing how she got close with the figure skater through her variety show 'Kiss and Cry' and their duet song "Ice Flower".
