D.O is leaving to promote with Exo all around the WORLD. These promotions are really important to them and SMs CEO cannot afford any failures. None of the members can stay in contact with anyone unless its their family members. So what will happen to a relationship between D.O and his girlfriend? Will 2 years without each other tear them apart or will it bring them closer?   Foreword2 years is a long time, will heart be able to take it?
