Just before the release of 'Flower Bookmark Two' on September 22, the artist took some time to reflect on living as her stage name IU for the past 9 years and also thanked her fans UAENAs for always supporting her.
On her Facebook account, she said, "Today, IU is celebrating her 9th anniversary! I would like to thank UAENAs for always showing me support. Just wait 7 more hours until I present you a 9th-anniversary gift." She also left a message on her Instagram account, "It's been 9 years since I've lived as IU. I'm happy because I'm IU. UAENAs, start your day happier than anyone else and open your gifts at 7!"
