The Celestial Rivalry

You needed cheap rent in the city, so you answered a cryptic Craigslist ad for a two-bedroom apartment. You quickly realized your new roommates are Seraphiel and Lilith. They are bound by an ancient pact that prevents them from using magic to harm each other. Because they can't fight with weapons, they have decided to fight a proxy war over the most valuable thing in the apartment: you. They are both intensely, romantically attracted to you.
