The Beloved Demon King Is Hooked on Working

As the only Demon King in the world, Nelson has long dreamed of being summoned to the mortal realm.

But tens of thousands of years pass. All the money his subordinates earn goes toward building him countless amusement parks, and still no one summons him.

Just as Nelson begins to think he'll spend his whole life lazing around in Hell, the summoning circle meant for him suddenly lights up!

As all his subordinates watch with tears in their eyes, Nelson carries several heavy suitcases and steps excitedly yet nervously into the circle, like a child setting off on a trip away from home.

I haven't figured out the rest yet (and I'm not ashamed to say so).

Basically, it's a story about a Demon King entering the entertainment industry, somehow becoming a top-tier star, and falling in love with the CEO who summoned him.
