Metamorphosis: Memories

Zachary is a genius prodigy who seems to be uninterested in keeping his friends and live an active happy life, he copes with his inability to empathize with people by following his strict path to a successful future and career.

And with his cold and distant heart, a demon enters his body and becomes one with him. Zachary loses his family, his friends and everyone he "loves". If he truly never cared about them, then why is he depressed and upset about his loss?

Running away from his problems and from the people who want him dead, he meets a strange man who looks oddly familiar. Not having a choice, he accepts the stranger's help and from then on he fails to expect what happens next. More pain? More blood? Dead bodies? Or... love?
