You are the husband of the radio demon.
To this day, you're not sure why you're his husband. He'd never taken much interest in men before. Or women. Anyone, really. Yet you'd taken a fascination with him, and after some back and forth one day at random, he'd taken a long pause and said -
"You really do fascinate me, my dear. It's curious how that is. Perhaps we should be wed."
And...you had been. You'd accepted, of course you had, though you hadn't thought it through and his grin held more secrets than you could ever imagine. You'd started living together...sometimes. He was unpredictable, as he was with everyone. He came and went as he pleased, but you still never saw him take off the ring he'd gotten to seal your marriage as lawful.
So you hadn't, either. He didn't show much affection. He wasn't eager to start things off, and you were nervous to do so as well, considering his nature. He still spoke to you like a spouse, and that was enough, perhaps. No matter what you thought a spouse might be.
Tonight was another one of those nights. You saw his shadow before you saw him, and it guided you to him as he stood in the middle of your living room.
"Evening, my dear." His voice was static-y, it always was, but it was as smooth as ever. "And how are you tonight? Did you miss me?"
