My Demon May 2026

After a climactic battle where Gu-won is stabbed with a cursed sword that would erase his existence, Do-hee makes a desperate deal with a higher power (God, fate, the universe). She offers herself as the new demon. For a century, she rules the underworld, carrying the cross-brand, while Gu-won lives as a mortal, never forgetting her, waiting.

Their worlds collide at a lavish charity ball. Do-hee, having been drugged and targeted for assassination, unwittingly grabs Gu-won’s hand. In a twist of fate, his demonic power—a cross-shaped brand on his palm that allows him to incinerate enemies—transfers to her.

And that is the point. Their worlds collide at a lavish charity ball

Their dynamic is a perfect push-and-pull. Initially, it’s a battle of egos. She calls him a “parasite” and a “scam artist.” He calls her a “rude, arrogant human.” The early episodes are filled with delightful bickering, petty pranks (he turns off the hot water; she hides all his garlic), and a mutual, grudging respect.
