Singer and actress IU has released a new song. On the 10th at 7 a.m., IU released the digital single "Bye, Summer" on various music platforms. The new song drew attention as it was released as a surprise without any prior announcement or separate promotion.

"Bye, Summer" was first revealed on the stage of the "2024 IU HEREH WORLD TOUR CONCERT ENCORE: THE WINNING," held last September at the Seoul World Cup Stadium. At that time, IU introduced the song by saying, "During this tour, summer felt unusually long. But I want to say that this summer spent with you all was the best summer. This is a song I want to share as much as the time we loved passionately." On stage, IU played the guitar herself while performing the song. The rain that fell during the performance stopped as the song ended, creating a unique scene.

The live clip quickly rose to the top of trending videos after its release, gaining significant attention. Fans expressed their love for IU's music by requesting an official release. This surprise release is interpreted as IU's way of giving back to her fans.

IU personally participated in writing and composing this song, collaborating with composer Seo Dong-hwan, who worked with her on "Love wins all." "Bye, Summer" captures the mood of early autumn when summer fades and cool breezes blow. IU's emotional vocals, refreshing band sound, and lyrical lyrics blend harmoniously, showcasing a high level of completion.

A lyric video was also released. Available on IU's official channel, this video captures short, fairy-tale-like summer memories, enhancing the song's atmosphere.

IU will hold a fan meeting titled "2025 IU FAN MEET-UP Bye, Summer" at KSPO DOME on September 13 and 14, where she will meet with fans. At the same time, she is filming her next drama, MBC's "21st Century Great Lady." IU is actively continuing both her singing and acting careers.

Since 2022, IU has been in a relationship with actor Lee Jong-suk. They have mentioned their relationship in public, attracting fans' interest. IU's music and acting activities continue to receive much love, and expectations for her future endeavors are high.
