Cheyish

Elliot Hawthorne, had transmigrated into the body of a struggling apprentice mage, and now had one simple goal, summon a small, harmless spirit to pass his magic academy’s final exam. But thanks to a mistranslation in an ancient grimoire, he instead summons Azrael, the almighty Demon King.

That would’ve been bad enough…. but then the spell accidentally binds them in an unbreakable marriage contract.

Now, Elliot is stuck with a possessive, dangerously powerful, and ridiculously affectionate demon husband who:

Carries him everywhere because "His cute little summoner’s feet shouldn’t touch the ground."

Summons hellfire just to keep Elliot warm when he complains about the cold.

Declares war on any kingdom that dares to call Elliot “single.”

Refuses to be unsummoned."Why would I leave? My husband is here."


Worse, every holy knight, exorcist, and jealous god now wants Elliot dead for "stealing" the most powerful demon in existence.. Stuck with a one-in-a-million system dungeon and a devilish Demon husband, Elliott's life is constantly on the brink of disaster...
But when Elliot starts uncovering secrets about the contract, he realizes…

Did I really summon him by accident? Or… was Azrael waiting for me all along?

One way or another, Elliott’s unlucky life becomes worse. An impending doom threatens the existence of the human and mortal worlds.

And as if that wasn’t enough, he’s also stuck with a Demon for a husband. 

But maybe, just maybe… being bound to a dangerously powerful Demon King isn’t the worst fate after all.

UPDATE: CONSISTENT POSTING FROM NOW ON!!

[BL] I Accidentally Summoned A Demon Husband Now He Won't Leave

Charles gave an indifferent nod as he responded, "Hmm, you will."

Elliot's eyes widened in horror, his face turning pale as he stared at Charles in disbelief. His voice shook with panic and anger. "What do you mean I'll die? And you're saying it so indifferently, like it doesn't even matter to you!"

Charles looked at him with a raised eyebrow, his expression unreadable. "What do you think?"

Elliot felt his heart sink. "You... you don't care?" he asked, his voice trembling with disbelief. A wave of hurt washed over him. Did Charles even consider him a friend?

With a resigned sigh, Charles rubbed the back of his neck, his face showing a hint of annoyance. "Alright, stop being dramatic..." He rolled his eyes, a half-amused smile playing at his lips. "It's not about me caring whether you die or not. It's about the fact that it won't change anything. If you're meant to die, you'll die. Simple as that."

A Devil's Deal!
