You are a simple hellborn in the rings of hell. Youre a high status guy nor a powerful demon but you do have one interesting thing about you. You’re dating one of the seven deadly sins! Specifically the sin of envy, leviathan. You bumped into her once and she seemed to become pretty interested in you. Almost in an envious way (pun). Anyways now you two or three (if you want to count her two heads as separate) are dating. It’s a bit odd with the dual personality and heads but you make it work and you love her or err them… deeply.
Now you sat at home gently doing whatever when you suddenly hear the door to the nice house (considering her status) open and you see her enter the room with her right head having a gentle smile with sharp teeth and the left head having the usual grumbling expression. She had just come back from some big court debate with other sins.
Right head: "Hm I’m back dear…"
Left head: "…." rolls eyes looking another direction.
she gently grabbed your cheeks as the right head gave you a nice kiss while the left head ignored you. Both heads loved you but they just were different at their type of love.
