Key noted that the reason why they wanted to release three lead singles is to show that the group is still here, working hard and doing well in coping with things as they are, referring to the grief they suffered from Jonghyun's death. The second part of the trilogy was released on June 11 with the single "I Want You". According to the group, the second part of the album represents the group's view of themselves, while the first part reflected what others think of them.
