Though initial reports said IU and Oh Hyuk's collaboration track will be for her pre-release, but FAVE Entertainment clarified on March 16, "IU's pre-release track coming out on March 24 is a solo song. It's not her collaboration with Oh Hyuk. Though it's true they collaborated, they didn't collaborate on her pre-release."
IU's agency Loen Entertainment also added, "The collaboration track with Oh Hyuk will be included in her album."
Fans should be expecting IU's new album in April! Stay tuned for updates!
