Bonding with the Devil

What would you do if your life is in the hands of a Demon? But this Demon is not just any ordinary, low-life demon, but a demon whose father is The King of Hell and that only means he’s the Prince.

One rainy evening while Angeline was walking home from her part-time job, a psychopath-maniac tried to hurt her. Without the strength to stop the person, suddenly, came out of nowhere a guy in red cloak appeared and save her. After saving her, the guy point at her face and introduce himself; "My name is Lucian, 2nd Prince of the Underworld. The son of the Devil which you all feared, hated...well, some of you loved and praised him"

Confused of what he was saying, Angeline asks him if there's anything she can do to pay him for saving her. Lucian gave her a smirk and said; "How about Bonding to a Devil...which is me".
