Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.

EP 01

Living in the Mist

November 24, 2023

Do Do-hee has a chaotic first encounter with the mysterious Jeong Gu-won — flustered and intrigued in equal measure — before becoming the target of a violent attack. Her survival comes at a price: a contract binding her to a demon she has not yet decided whether to believe in.

EP 02

Everyone Has a Demon in Their Heart

November 25, 2023

Gu-won realizes that Do-hee holds the key to his vanished powers — and begins the delicate, increasingly humiliating task of trying to reclaim them. His attempts backfire spectacularly. A demon who has lived 200 years is apparently not prepared for a woman who refuses to be intimidated.

EP 03

Joining Hands With a Demon

December 1, 2023

Another attempt on Do-hee’s life leaves her with a decision: run alone or hire the most unusual bodyguard available. She knows what he is. She hires him anyway. She also starts pulling on the thread of a recent death that doesn’t quite add up — and Gu-won finds himself unexpectedly useful in ways that have nothing to do with his tattoo.

EP 04

Sweet but Dangerous

December 2, 2023

Do-hee proposes a contract marriage — practical, mutual, emotionally uncomplicated. Gu-won refuses, which is not how this usually goes. The investigation into Chairwoman Joo’s suspicious death deepens, and Gu-won hits an unexpected blockage in whatever remains of his powers. The show’s central mystery clicks into focus for the first time.

EP 05

A Deal Worth Making

December 8, 2023

The investigation into Chairwoman Joo’s death grows more tangled as threats from within Mirae Group escalate. Do-hee and Gu-won work in closer proximity than either is comfortable admitting — and Gu-won begins to notice that what he’s feeling around her doesn’t map onto anything in his 200 years of emotional vocabulary.

EP 06

Into the Wheel of Fortune

December 9, 2023

After Gu-won saves Do-hee in a moment that leaves both of them shaken, she suddenly has more marriage proposals than she knows what to do with. She chooses one. And at the wedding — in the middle of a ceremony that should feel like a solution — an alarming face appears among the guests.

EP 07

Stained Relationships

December 15, 2023

Married life under the same roof is exactly as awkward as expected — and considerably more charged than either party will acknowledge. Meanwhile, Ju Seok-hoon watches Gu-won with growing suspicion. He can’t prove what he suspects. But he knows something is wrong with a man who never seems fully human.

EP 08

When the Fire Starts

December 16, 2023

Tensions peak as the antagonist’s identity begins to crystallize. Gu-won rescues Do-hee from a gas station fire in a scene that functions as a turning point — not just for the action plot, but for both of them personally. The drama crosses a line it cannot walk back from, and doesn’t try to.

EP 09

The Unmasked Truth

December 22, 2023

The relationship that was supposed to be a transaction has become something else entirely — and both of them know it. As Do-hee and Gu-won stop pretending, Gu-won begins to experience strange and alarming shifts in his remaining abilities. A larger threat, older than their contract, starts to take shape.

EP 10

Breaking Through the Shell

December 23, 2023

The truth about the deal Do-hee’s father made with Gu-won long ago begins to surface — and the implications are more complicated than anyone anticipated. The threat against them deepens. Their bond is tested not by outside forces but by something that happened before Do-hee was born.

EP 11

Contracts Written in the Past

January 5, 2024

The secret of Do-hee’s past unravels in full — the fateful contract her father once signed, what it cost, and what it means for who she is to Gu-won now. The emotional fallout is brutal. Do-hee is left questioning whether anything between them was real, or whether she was always just a piece in someone else’s arrangement.

EP 12

The Price of Old Deals

January 6, 2024

The revelation about the old contract strains the marriage to its limit. Do-hee’s initial shock curdles into something harder to parse — not just betrayal but the specific grief of realizing the person you trusted had been keeping something this large. Noh Suk-min escalates, sensing an opening in the fracture between them.

EP 13

Standing on the Same Side

January 12, 2024

Do-hee and Gu-won regroup and begin gathering evidence against their true enemy as attacks on her grow more relentless. Ju Seok-hoon makes a choice — to stand beside the couple rather than against them — that settles the second-lead question more gracefully than most dramas manage. An unlikely alliance forms with time running out.

EP 14

Desperate Measures

January 13, 2024

Noh Suk-min’s desperation tips into something extreme — he disfigures himself in a bid to evade the net closing around him. Gu-won and his allies combine forces in a push to end this. The pieces are in place. The cost of those pieces is about to become clear.

EP 15

The Price He Pays

January 19, 2024

Gu-won makes a sacrifice to protect Do-hee — and disappears from the mortal world without explanation. Do-hee is left devastated. Those around her grieve. She refuses to accept it as an ending, holding onto something that looks a lot like faith for a woman who stopped believing in anything a long time ago.

EP 16

What Remains After the Contract Ends

January 20, 2024

The finale resolves all major threads — Noh Suk-min is imprisoned, Gu-won returns to Do-hee, and the couple chooses to spend whatever time they have together despite the impossible gap between a mortal life and an immortal one. Jin Ga-yeong’s arc reaches its most quietly powerful moment in the final scene. Ju Seok-hoon bows out with grace. Not everything is perfect. The parts that matter land.

Full spoilers ahead — everything that happens in the finale and what it all means.

The Sacrifice and the Silence. Episode 15 ends with Gu-won making the choice he has been avoiding — using what remains of his demonic power to protect Do-hee from the final threat, and in doing so, vanishing from the mortal world entirely. He doesn’t explain. He doesn’t say goodbye. He is simply gone, and Do-hee is left in the aftermath of a loss that nobody around her quite knows how to name, because how do you grieve someone who wasn’t supposed to be able to die?

The Villain Gets His Answer. Noh Suk-min — the man behind the murders, the conspiracies, and the years of quiet violence against Do-hee — is ultimately imprisoned. The show handles his fate with the kind of restraint that frustrated many viewers: he survives. He is not destroyed. He is simply removed. For a drama that built him as such a persistent threat, the ending feels like a closed door rather than a reckoning, and the gap between what the story promised and what it delivered is the finale’s most honest weakness.

Gu-won Comes Back. He returns far sooner than expected — much sooner than the mythology of his disappearance seemed to warrant — and the reunion with Do-hee is warm but slightly rushed, as though the show ran out of room to sit with the weight of his absence. What works anyway is the clarity of what they choose: Do-hee is mortal and Gu-won is immortal, and neither of them pretends this is sustainable forever. They choose each other for the time they have, and the show treats that as enough — which, given how rarely K-drama fantasy romances are honest about this particular math, it is.

Jin Ga-yeong’s Full Circle. The finale’s most earned moment belongs to a supporting character. Jin Ga-yeong — whose childhood abuse was revealed earlier in the series and whose arc tracked a woman still carrying the weight of what was done to her — encounters a young girl being hurt by her father in the final scene. Instead of looking away, she steps in. She protects the child the way Gu-won once protected her, and in doing so, she breaks the cycle that defined her. It is the quietest scene in the finale and the one that sticks longest.

What the Drama Was Actually About. My Demon is at its most interesting not in its supernatural mechanics — which never quite cohere into a consistent internal logic — but in what it does with the idea that the most dangerous contracts are the ones made out of love. Do-hee’s father signed his soul away for her survival. Gu-won bound himself to a woman for centuries without understanding why she felt different from everyone else he’d ever dealt with. The contract marriage between them started as convenience and became, quietly, the truest thing either of them had ever agreed to. A 200-year-old demon learns to feel something. It turns out that was the deal all along.
