An Angel's Heart (Sebastian x Angel Reader, Black Butler/Kuroshitsuji)
21 parts Complete You were an Angel craving chaos... He was a demon seeking peace...
As an Angel you didn't remember much about your past, everything you knew was what other Angels had told you. But why should you believe them when they treated others, especially demons, so harshly over nothing? You could't bear to watch them be so cruel, you needed to prove to them that nothing was truly ever evil.
But once the facade of the Angels and Demons surrounding you fade away, you're not quite sure what to believe anymore.
(I don't own Black Butler, any of the characters or you. Obviously. Also, I am currently editing this story which means I'll add and remove some parts of this fanfiction. So please forgive me if some things don't make much sense.)
