Due to the tragic event in the province of Jindo, wherein a ferry sank on April 16, Samsung Music has postponed their EXO "Overdose" comeback event for an indefinite time.
Samsung Music wrote on their official event homepage, stating,
To the customers of Samsung Music.
We send our deep condolences to the victims and their families who are experiencing a large pain due to this unfortunate accident. Samsung Music has decided to indefinitely suspend all events, including the EXO special event. We ask for understanding of all our members. We will be making announcements later on when we will resume the event. Also, the information of those who entered for the fansigning is still valid, and will be reflected regularly when the event is resumed.
As reported recently, EXO has also delayed their comeback until further notice because of the Sewol ferry incident.
