Meanwhile, for the first time in 13 years since her debut, IU released a double-title track album, including Lilac and Coin.
The female star flaunted two different concepts, as while she showed off her usual cheerful and fluttering image in the former, she challenged herself for the latter with an attempt to rap, killing it nevertheless.
IU wrote all 10 songs (including co-written lyrics) in her fifth full-length, which summarized her 20s. Upon its release, all tracks entered domestic and international music charts, and the title track Lilac also achieved a Perfect All Kill (PAK).
Aside from digital charts, the female idol s physical sales also broke her personal record, selling 270,000 album copies for the first week of its release.
