IU claimed that her legs thickened.
On October 17, IU appeared on SBS' 'Cultwo Show' and talked about her comeback.
DJ Jung Chan-woo asked, "Your new song 'The Red Shoes' made a chart 'all-kill'. Your song seems like a musical and it has moves. Isn't it hard for you?"
IU answered, "It's very hard. Because I practiced a lot for 'The Red Shoes', my calves got thicker."
Jung Chan-woo responded, "If that's what you call 'thicker', then you need to practice a lot more from now on," making IU laugh.
Netizens commented, "IU said she was on a diet and now she says her calves got thicker. What is she saying?", "That is thick? Where?", "It doesn't make sense", and more.
