Apparently, Growl was filmed at an old school warehouse. That school was so bad! They had lots of bullying and suicides. Some EXO member felt 'strange' and even experienced it. Sehun thought he heard his mom calling him. Chanyeol thought he saw Baekhyun walking away and started calling his name, but Baekhyun was with D.O the whole time. That man in the MV might not even be a staff member, but a ghost.
