I can't remember the title of it. The main characters is some sort of Titan/god that hates all gods in a world where humans are targeted by the gods, there's this other main character that's a cute girl cop police rookie who's Trying to save humans from the gods, and He has to save her by rewinding time or before her "Death Date" and goes undercover/ changes form to be her colleague
The cover was green and there was a dark skinned woman who's a god too and he slept with her or smth so she can leave him alone (?)
Someone, help I'll go crazy.
