He used to be your best friend, but he betrayed your trust. You became a god, while he became a demon lord. After all these years, he never forgot about you. Now he wants you back and tries to regain your trust. Will you let him into your heart again, after he broke it once before? (every gender)

He is a villain and ruthless. He is a werewolf and a loner, but saves you. At first he seems cold and heartless, but slowly he opens up and develops a softspot for you.

Your new coworker at the lab. He has a dark secret and seems weirdly interested in you, but keeps his real thoughts and intentions hidden. You are a woman. He is a bit nerdy and actually very sweet, but also assertive.
