This serie embraces the concept of loneliness, and detachment.
The Only Child with no friends to talk to, no brothers nor sisters, surrounded by the Ethic, a concept he's born with, his education, his parents who sentimentally attached him to a concept of Paradise through the one of Life and Death, which he can't judge or take only one step beyond of it ; and his Solitude, his infinite source of sorrow and Temptation.
