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

<p>Answering his question of the inspectors cleared his throat harshly, his eyes narrowing as he delivered the punishment. "Your punishment will be a night in the 'Abyssal Chamber' with mana chains binding your limbs. You will be left in complete darkness, with mana-consuming specters that will drain your energy slowly, leaving you weak and vulnerable. These specters will also invade your mind, preying on your fears, twisting them into horrifying illusions that can break even the strongest of minds. You will hear screams—echoes of past victims who lost their sanity within those walls. Most who enter the Abyssal Chamber come out scarred for life, if they ever come out at all. No food. No water. Just you, the darkness, and the spirits of despair."</p>

<p>The cruelty of the punishment made Elliot shiver uncontrollably. This was simply inhumane, and he was going to face this? At this rate, he wasn't sure he would come out alive… or even sane.</p>
