Sad memories unconsciously stimulate the nightmares. The dream will disappear when the reality touches it.

  White angels live in the White Heaven, black angels live in the Black Heaven.

Because angels are not supposed to have emotions and lust. What if love appears between one of the white angel named Dio and one of the black angel named Kai?
