IU Bids Farewell to Summer with Surprise 'Bye, Summer' Single

On September 10, 2025, K-pop artist IU delighted her fans by unexpectedly releasing the digital single 'Bye, Summer'. The emotive ballad blends IU's lyrical vocals with a breezy band sound, evoking the last cool winds of the season and echoing the audience buzz since its stage preview.

The song first gained attention during IU's world tour encore performance in Seoul last September, where she performed it on guitar as the rain eased near the finale. The subsequent live clip and fan requests paved the way for an official release, which now comes paired with a lyric video. The visual tracks two young people building memories in the sun before parting at season's end, mirroring the single's tender narrative arc.

While promoting the new release, IU is also currently filming the upcoming MBC romance drama '21st Century Grand Lady', set in a modern constitutional monarchy. She plays Seong Hee-joo, a driven chaebol heiress who enters a strategic marriage with Prince Lee Wan, portrayed by Byun Woo-seok, in a class-crossing narrative developed from an award-winning script.
