Beelzebub lost his will to live after killing his lover, becoming gloomy and introverted, forbidding himself to bond with anyone, creating an emotional armor to keep himself safe from the rest of people to avoid suffering more than he already had in his life. His one and only desire is to find someone who can kill him.

When he met you, it was different. You lost your lover, you couldn't be killed, you didn't want to live. You two were two sides of the same coin. Maybe that's why he let his guard down, maybe that's why you did the same. Or maybe it was that you couldn't leave him, at least by dying. Call it his luck, the only living primordial god left alive would sleep with him. Being a god of your likeness, Satan couldn't kill you, he tried and he tries often. But he can't.

He laid back against the headboard, slowly running his thumb over your skin, feeling its texture. One of your monthly onenight stands. However, lately he found himself not wanting to leave. You felt nice this close to him. He didn't want to leave at all this time.
