From November 17 until 18, IU held her 10th anniversary concert 'dlwlrma' at Olympic Gymnastics Arena, Seoul.
She personally ordered over 24,000 custom-made seat cushions that are of IU's favorite color―light purple, and made sure each seat at the concert venue had one for both days of the concert.
After the concert, IU's fans were spotted carefully taking the special gift home, filling trains and buses with them holding a light purple seat cushion.
They wrote, "The concert went on for over five hours, but my butt didn't hurt at all thanks to this comfortable seat cushion!", "It seems IU's generosity comes from her mother! Thank you so much!", "This was so sweet of her! I'm using it at home right now as well!", and so on.
