The group EXO canceled the schedule in the music industry.
SM Entertainment said on the 25th, "We will cancel the EXO 6th album 'OBSESSION' press Concert schedule scheduled for 11 am on the 27th."
This appears to be a decision to mourn the death of the late Goo Hara.
AOA, which had planned to open a showcase on Wednesday, also canceled the schedule in memory of fellow singer Goo Hara; singer Crush also delayed the release of the new album.
