... Is she a sin...
Are her eyes a symbol of sin?
Is her long hair a symbol of sin?
Are her wings a symbol of sin?
... Or, her existence... Is a sin...
Such a cruel heart, leaving traces of sin on her body that will never be destroyed...
Maybe... She really is what her mother calls... A monster.
But he said her wings were beautiful, and he would rather she hate him than regret plundering them...
