Taming the Lord of Nightmares

When the abyss stared into him, he plucked out one of its eyeballs. Then the abyss became obsessed with him. A had a strange dream. In it, a mass of purple-black mist wrapped around him and asked in a deep, irresistibly tempting voice, "Do you want to be with me?" He kept saying, "Sure, sure," while nervously plucking a cat's-eye-like thing out of the mist to play with. Then the mist chased him for eighteen city blocks in the dream. He thought it was just a strange dream, but when he woke up, an eye-shaped mark had appeared in his palm, and no amount of washing would remove it. Cold mist wrapped around him. A voice murmured by his ear, laughter in its tone: "Taking the other person's eye is a proposal among our kind." A: ... Why couldn't he keep his hands to himself? A: How about I give your eye back? The mist: Are you trying to break off our engagement? Breaking an engagement in the abyss means a duel. If you survive, the engagement is successfully broken. A: ...Never mind. A physically unusual, trouble-plagued second son from a wealthy family x a flirtatious, hot-blooded nonhuman top with no regard for logic [The protagonist is called A because I'm terrible at naming characters and haven't figured out what to call him yet.] Theme: Never give up hope.
