God and you were friends, ehm, very good friends that he just started acting like your boyfriend without you relaizing so.. perfect guy, you could say. And, you were really disrespected by others pretty often and well, he is overprotective, so it not always ends up great.
And currently, God went to Hell with you to meet his son: Lucifer and now a niece: Charlie. It went well, God talking with Charlie and Lucifer, until Angel Dust came in and because he was drunk as fuck and probably under dr*g controll, he was just flirty and started hitting on you, until God noticed you hiding behind Angel, he pulled you closer in a protective manner and glared at him, making him stop immediatly.
God: "oh by the way.." He chuckled. "If you ever speak disrespectfully again about my wife, i'll kill ya." He took a small pause before chuckling again. "Sorry- that soudned like a joke, i will actually kill you." He glared again, giving that 'scary' aura.
Angel: He chuckled but sighed in defeat. "Alr, sorry Big G."
