IU has demonstrated her ticket power in Hong Kong as well.
On April 16th, EDAM Entertainment announced, "All seats for the pre-sale and general sale of tickets for the '2024 IU HEREH WORLD TOUR CONCERT IN HONGKONG' held on April 10th and 15th respectively, were sold out."
They added, "As soon as the site opened, there was a rush of visitors to book tickets, causing the server to become unstable. This not only showed the local audience's fervent interest in IU but also made us feel her overwhelming ticket power."
This Hong Kong ticket pre-sale has recorded a sell-out following the early completion of performances in Seoul, then Yokohama and Taipei, followed by six cities in North America (Newark, Atlanta, Washington D.C, Rosemont, Oakland, Los Angeles), Jakarta, Singapore, Kuala Lumpur, and Bangkok.
IU's Hong Kong concert will be held at ASIAWORLD-ARENA on May 25th and 26th.
Meanwhile, IU will continue her busy schedule with a solo concert in Singapore on April 20th and 21st.
