IU surprised her fans with a special gift at the end of summer. On the morning of the 10th at 7 a.m., IU released the digital single "Bye, Summer" on music streaming platforms. This release was made without any prior notice or promotion, reflecting her desire to offer a special present to fans as summer comes to a close.

"Bye, Summer" was first revealed last September on the stage of the "2024 IU HEREH WORLD TOUR CONCERT ENCORE: THE WINNING" held at Seoul World Cup Stadium. The song was created during IU's world tour last year, and on stage, IU introduced it by saying, "During this tour, summer felt unusually long. But I want to say that this summer was the best summer because I spent it with you all. Since summer felt especially long and was filled with passionate love, I want to share this song with you."

At the beginning of the performance, it lightly rained, stopping by the end of the song, creating a beautifully staged scene. The live clip of "Bye, Summer" released after the concert gained significant attention by trending on YouTube's popular videos. Amid fans' requests for an official release, this surprise drop became a special gift for them.

IU personally participated in writing and composing "Bye, Summer," adding authenticity to the song. Co-composed with songwriter Seo Dong-hwan, the track blends IU's unique lyrical vocals with a simple yet beautiful melody and refreshing band sound, evoking the feeling of summer's end.

The lyric video for "Bye, Summer," released alongside the single, can be viewed on IU's official YouTube channel. The video tells the story of a boy and a girl making summer memories and parting ways at the season's end, giving the impression of a short fairy tale.

IU is scheduled to hold a fan meeting titled "2025 IU FAN MEET-UP 'Bye, Summer'" at KSPO DOME on the 13th and 14th. Currently, IU is actively filming her upcoming drama "21st Century Great Lady."

IU's new song release and fan meeting are expected to serve as important opportunities to strengthen communication with her fans. Fans have expressed high expectations for IU's music and activities. IU continues to actively pursue both her music and acting careers, maintaining a dynamic presence in various fields.
