Dean Winchester didn't consider himself capable of love....until he met (Y/N) (L/N). (Y/N) breathed magic into his life, literally. He took his own sweet time coming to terms with his feelings for her - his biggest mistake. The Mark of Cain grows malevolent everyday, forcing him into actions which drive (Y/N) away from him, further away than he could bridge. Now Dean is facing two fights - for you, to win you back and with himself, to win against the mark. And he has a decision to make in the face of inevitable death.
