They were angels that were sent to Earth for a secret mission. SHINee are all angels that disguise themselves in the human world. For some reason the sky keeps on changing and one day they noticed a face in the sky. Evil is approaching. They changed into their warrior angel forms and ready themselves for action. Minho- the lead fighter- did not listen and risked it. He fought on his own and died. The demon then possessed him and he captured Onew and Taemin who was looking for him. "Minho" ripped off Taemin's wings and threw him down back to earth.

Taemin- an angel who lost his wings roamed through earth for centuries searching for the enemy that tore away his wings and position of being an angel. He has been searching but he could no longer remember the person's face but only remember the empty feeling inside of him.

Minho- a human- a person- the one- the enemy- of Lee Taemin. He is nothing but a mere human being who is living a normal life. One day, a new student joined his school and changed his life forever.

Onew, Key, & Jonghyun- Former warrior angels who conquered evil. During the war, they were hit down to Earth and lost their angel memories. God has no choice but to leave them down on Earth until they regain their memories. They are friends with the human Minho and one day found a new friend named Taemin. God must wait for them to fix the misunderstanding and destroy the rising human-devil- only then, can they return back to Heaven.
