UNKNOWN

Everyone... no! The world knows their existence. They successfully built a flag of significance in this rotten world. They dominated the universe as world stars, as performers, as mere idols... as 'EXO,' the twelve-member boy idol group.

But everything had changed when the three of them left. Everything went to chaos and lost balance. World was shaken, humans that developed bonds to them suffered... but more importantly, the universe started crumbling, losing three stars that was supposed to be twelve.

In the midst of pain of everyone, the members, the fans... is another being agonizing from the asphyxiating turn of events. Another one who can be said as the most affected, devastated, ruined...

EXO's unknown member.
