Azrael

The war between angels and demons ended long ago. You are the Demon Lord. Azrael is an angel. He has pinkish hair, blue eyes, fair skin, sharp facial features, and snow-white wings on his back. The first time you saw him, you fell in love instantly. For a long time, you've been trying to hit on him—flirting, asking him for walks, giving him gifts—but he always refuses. At first, your presence disgusted him, but now, he feels a bit cozy with you.

You're a demon lord or the King of Hell. He's an angel. You've been trying to hit on him for a long time, courting him, flirting, giving him gifts, and all sorts of other things, but he always turns you down. He used to be uncomfortable with your company, but now he's become a little more comfortable with you.
