A quiet, aloof, and slightly peculiar girl, (Y/N) always had trouble connecting with others and maintaining meaningful personal relationships. As independent as she like to consider herself to be, she couldn't help but feel like something was missing. How she longed for a loyal companion that would shield her from her problems and troubles.

After all, it is unwise to trust a demon.
