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

EP 01

The Boy Who Brought Death

Dec 18, 2021

Long before he’s anything resembling a monster, Dan Hwal is just a boy blamed for every misfortune that touches his village — cursed by rumor before he’s cursed by anything supernatural. The premiere waits until he’s a grown military officer hunting an actual monster to spring its reversal: the hunt doesn’t end with a kill, it ends with Hwal becoming exactly what he was sent to destroy.

EP 02

Six Hundred Years, One Grudge

Dec 18, 2021

Newly immortal and freshly grieving a family he can never see again, Hwal turns his loss into a single sustaining purpose — track down the woman who stole his soul, across however many lifetimes it takes. The show jumps straight to the ledger it’s been keeping since episode one: six hundred years of pursuit, and it’s finally led him to a woman living an ordinary life in the present day.

EP 03

Hiding in Plain Sight

Dec 19, 2021

Min Sang-un has built an entire quiet life around not being found, sister Si-ho at her side, and none of it is enough once Dan Hwal decides she’s the woman he’s been hunting for centuries. The episode plays her fear as entirely earned — she has no context for what’s chasing her, only the fact that it never stops.

EP 04

The Weight of a Curse She Didn’t Choose

Dec 19, 2021

Hwal’s pursuit stops being a background threat and becomes Sang-un’s whole reality, forcing her to reckon with a connection to his suffering that she never agreed to and doesn’t understand. The mystery of who the ‘real’ Bulgasal actually is starts working its way to the surface here, complicating a hunt that looked simple in episode one.

EP 05

An Uneasy Truce

Dec 25, 2021

Neither of them plans this alliance — Hwal and Sang-un back into it once it becomes clear that whatever is happening between them is a smaller piece of a longer game run by Ok Eul-tae. It’s the first episode where hunter and hunted occupy the same side of a fight, however briefly and however little either of them trusts it.

EP 06

Fragments of Who They Were

Dec 25, 2021

Detective Kwon Ho-yeol joins the group, and with him comes the first real excavation of who everyone actually was in a previous life. The show treats reincarnation less as a twist and more as an audit — every character owes a debt from a life they can barely remember, and the bill is finally coming due.

EP 07

Cracks in the Alliance

Jan 1, 2022

Trust between Hwal and Sang-un turns out to be a lot more fragile than either wants to admit, and conflicting memories of who betrayed whom in a past life start doing real damage in the present. Nobody in this group can fully vouch for who they used to be, which makes trusting who they are now a genuinely difficult ask.

EP 08

The Puppet Master

Jan 1, 2022

Ok Eul-tae stops hiding how much he’s been engineering, and the show finally shows its hand on just how far his manipulation reaches. His motive isn’t complicated — he wants to keep living, on his own terms, for as long as it takes — but the damage he’s willing to do to protect that is the episode’s real reveal.

EP 09

What the Bulgasal Lore Won’t Say

Jan 8, 2022

The group finally gets access to the older history of what a Bulgasal actually is, and with it comes the first real theory for how to end the cycle instead of just surviving inside it. Hope, in this show, comes with a catch — every answer they find opens up a more dangerous question underneath it.

EP 10

A Family Under Siege

Jan 8, 2022

Eul-tae doesn’t wait to be found — he comes straight to Hwal’s door looking for Sang-un, while a monster from someone’s past life grabs Do-yoon as leverage. The episode is blunt about what’s actually at stake: not just two cursed people settling an old score, but the makeshift family that’s formed around them.

EP 11

What Si-ho Is Willing to Risk

Jan 15, 2022

Hwal decides imprisoning Eul-tae is the only way forward, while Si-ho goes digging through Sang-un’s past life for anything that might keep her sister alive. The urgency here isn’t abstract — everyone in this group has already lost people to this curse once, and nobody’s interested in doing it twice.

EP 12

A Thousand Years Ago

Jan 15, 2022

Eul-tae says something that Hwal can’t let go, and the investigation finally reaches back a full thousand years to find where all of this actually started. What comes back isn’t a clean villain origin — it’s a tangle of betrayal and misunderstanding old enough that nobody left alive can fully vouch for either side.

EP 13

Two Versions of the Same Memory

Jan 22, 2022

Hwal and Sang-un finally sit with the fact that they remember the same past differently, and reconciling those two versions turns out to be harder than fighting Eul-tae directly. Eul-tae, meanwhile, stops being reactive — he starts planning to take away everything Hwal has left, on purpose.

EP 14

The Moral Compass

Jan 22, 2022

Vengeance is right there for Hwal to take, and Sang-un spends the episode talking him out of the version of himself that would take it without hesitation. It’s the clearest the show has been about what her actual role in his life is — not prize, not obstacle, but the one person keeping him human enough to still deserve saving.

EP 15

The Well

Jan 29, 2022

Hwal, Sang-un, and Ho-yeol corner Eul-tae for what should be the final confrontation, except the show has one more person’s hidden agenda to reveal before it lets anyone call this finished. Whoever the audience assumed was the last obstacle, it turns out there’s another one standing just behind him.

EP 16

A New Beginning

Feb 6, 2022

The thousand-year-old backstory finally closes the loop on how the Bulgasals’ curse began, and closing that loop is what actually breaks it — not brute force, but understanding. Dan Hwal and Min Sang-un get the ending the series has been arguing they deserve: a chance at a life that isn’t measured in centuries of debt. Ok Eul-tae doesn’t get the same mercy, and the show doesn’t pretend he’s earned it.

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

What literally happens The finale traces the curse back to a betrayal a thousand years old — the origin point for Dan Hwal, Min Sang-un, and Ok Eul-tae’s entwined fates — and resolves it not through a bigger fight but through finally naming what actually happened back then. With the truth on the table, Hwal and Sang-un make the sacrifice needed to end the cycle of reincarnation and revenge, while Eul-tae, unwilling to let go of his own immortality, is the one who doesn’t survive the reckoning.

What breaking the curse actually costs The show is careful not to make the ending free. Centuries of pursuit, resentment, and death don’t just cancel out because the truth finally surfaces — Hwal and Sang-un have to actively choose to let go of six hundred years of grievance, which is a harder ask than defeating Eul-tae ever was. The curse breaks because two people decide the debt is paid, not because the math resolves itself.

Ok Eul-tae’s ending, and why it isn’t tragic Eul-tae gets no redemption arc, and Bulgasal doesn’t seem interested in giving him one. He wanted to keep living regardless of who paid for it, and the finale treats that refusal to change as the actual reason he loses — not because he’s weaker than Hwal, but because he never stops choosing himself over everyone tangled in his curse. The show reserves its sympathy for the people willing to give something up.

Three ways to read the finale One reading is straightforward genre catharsis: cursed lovers break the curse, villain loses, credits roll. A second reading treats the whole series as an argument about grief — that Hwal spent six centuries mistaking rage for mourning, and the ending is really about him learning the difference. A third, colder reading points out that breaking the cycle still required somebody to die for it, which complicates any version of this ending that wants to feel purely happy.

Why episode one hits differently once you know the ending Go back to the boy blamed for his village’s misfortunes in episode one, and the finale reframes him entirely — not as a monster in waiting, but as someone who spent his entire life, human and immortal both, being punished for things that were never fully his fault. Bulgasal spends sixteen episodes building toward the idea that the curse was never really about blood. It was about who gets to stop being blamed.
