IU released a new album named Chat-Sire. IU is known for her fantasy concepts and this time she did a alice in wonderland theme. Her comeback mv is Twenty-Three and she wrote it herself.
I know IU since her debut in 2008 and she is one of my favorite solo artists. I am a bit sad that IU will not perform this song on music shows but she is currently busy to prepare for her concert and she puts all her energy in it.
