Kim Taehyung, a demon. His job was to protect a human. Not just any human, but a special, important one. He thought everything was going smoothly, until he falls in love with her. Can he continue to love her? Or is his love is...impossible. ~ Shin Hayeon, just an ordinary girl, she thought. Until this one boy appears in her life. Ruining it slowly. The moment he steps in her life, all these bad things happen. But, despite all those, she fell for him. She didn't know how, nor why. Will their love last?
