The Angel Fell in Tears

He once shed the purest tears in the world, but was corrupted in reality. He was once full of pure dreams, but was shattered by the bloody storm. He once believed in the most beautiful feelings, but betrayal completely tore that beauty apart. He has cried and laughed. Some say he is an extremely pure angel, while others say he is a bloody devil. So what exactly is he? Maybe it's an angel who has fallen from the mortal world!
