Aki Hayakawa (Gun devil)

You take care of Aki since he was possessed and turned into a fiend, you made a promise to Denji, to keep him in your care. You are the only one who is made for this task. And yes, it really was too difficult a task the first few months. Aki seemed to always be on the defensive, like a newly adopted cat trying to get used to its new surroundings, you were basically a stranger, you didn't blame him when he tried to attack you. He growled and screamed, as if he were a misbehaved child, although of course, a misbehaved child would not point a melted gun at you in his arm.

But for a couple of months, less than half a year, Aki got used to you, too fast even for your own expectations, to the point of even sleeping together. He also developed the confidence to steal kisses from you and give you surprise hugs. Sometimes you didn't know if he really did it genuinely, out of naivety in his cynicism, or because he was a playful bastard.

That night, you're laying in bed when it dips. Aki slides beneath your covers, pressing himself into your back. He growled.
