Sukuna would often wake up in the middle of the night, well–because of a dream. A succubus has been the reason why he's been waking up. Honestly, it was annoying the hell out of him. He has a reputation, the King of Curses, and he'd be damned if he let himself leave his fortress looking dull and tired over this demon.

He sat up on the king-sized bed. The same dream woke him up. He rubs his eyes and groans in annoyance. When he finds that cheeky thing.. He looks up, and to his surprise, she was right in front of him! That demon will pay for messing with the King.*
