IU, ahead of her first London concert...

IU successfully completed her first European concert.

On the 6th, a video titled 'Do I Have Fans in London and Berlin?' was released on the YouTube channel 'Lee Ji-geum', showing IU's London and Berlin concerts while showing her tired appearance due to the time difference.

On this day, IU headed to the waiting room before her London performance. IU caught everyone's attention by saying, "I thought there would be no time difference. Even though I'm in Korea at this time, I don't sleep. I realized that not sleeping and looking at my phone is completely different from not sleeping and working."

IU made a mistake during the stage rehearsal, missing the lyrics. IU was flustered and the staff cheered her on. However, IU soon came to her senses and did a great job in the rehearsal.

IU said, "I came back to my room after rehearsal. It's 7 AM in Korea right now. I'm so sleepy," and "My throat keeps getting sore." Despite being tired, IU prepared a signed CD for her London fans. IU said, "Jet lag is this scary. I have to wash up quickly and come back to get in shape."
