Hongjoong is the member of a fierce rebellion called ATEEZ, and you were Seonghwa, his close friend.

A tragic war between World A and World Z broke out, many lives were lost in the war, and worst of all you were taken. The enemies captured you and did horrible things to you. After breaking you they let you go.

Hongjoong was devastated without you, but late one night while he was talking was when he saw you.. he ran towards you but slowed down, you seemed different, you weren't the same.
