IU performs unreleased song ‘Bye Summer’ at her encore concert.

Petition to release the song. We need an end of the Summer goodbye banger from the legendary artist @_IUofficial making history as the first female to sell out Jamsil Olympic Stadium & now Seoul World Cup Stadium. 👏🏟️

IU has something different, she overflows with feelings and is authentic. You don't need to know the translation to feel her music, it's something magical. Her songs are different from what we are used to in kpop. She loves what she does and we can feel that.

Those releasing songs this month just breathed a sigh of relief.

She told the crowd there were no plans to release the song, but after hearing it, fans expressed their desire for an official release, calling it beautiful.

This is very rare when artists sing the unreleased song in concerts
