My Fake Fiancé Is the War God

Olympian priestess Serena saves the poisoned war god Ares by sharing his bed, and the night leaves her pregnant. Desperate to shield her unborn child, she strikes a bargain with the Fates that costs her memories and part of her lifespan, leaving her unable to recall who the father is. When she is pulled back to Ares, she discovers that her closest friend Hera has taken over her identity. Though the frosty god should have no interest in her, he feels strangely pulled toward Serena and proposes that they pretend to be engaged.
