Captors seek a blind girl matching a portrait; one who can see is about to be killed when she offers to be blind, and is renamed Jin Bu-yeon.
The cult leader preaches eternal life through the ice stone, then orders the girl who witnessed it to win over Jin Ho-gyeong and bring her there.
Flashback: a gifted girl senses the ice stone under Lake Gyeongcheondaeho, and her jealous father turns on her to seize it.
An old woman feeds a blind girl who has lost her memory, offers her a home and gives her the name of her late granddaughter.
While the household hunts for a missing young lady, a delivery boy meets a stunning stranger who barters for his liquor and vanishes.
Breaking through a barrier, Jang Uk finds a woman piling stones to climb a wall; she begs to leave with him and sees the ice stone inside him.
Jang Uk refuses to free her, then asks what she did to deserve the room; she says she died long ago and should not exist.
After her sister checks on her, Jang Uk embeds more steps in the wall for Bu-yeon, saying they are guilty of the same crime.
Cho-yeon learns of a sudden wedding and questions who her sister really is; their mother tells Bu-yeon she will wed but never leave her room.
Bu-yeon pays an inn madam for news of her betrothed and hears a ranking of Daeho's eligible men, then is chased off as a thief.
Bu-yeon accosts strangers hoping for her groom from the Seo family, misses Seo Yul's arrival, and fixes her eyes on Jang Uk instead.
Over chicken, the escaped woman names herself as Jinyowon's long-dead eldest daughter, explains her trap, and asks Jang Uk to marry her.
Bu-yeon argues Jang Uk is the perfect husband to defy her mother and insists he admire her face; he concedes she is pretty and walks off.
Bu-yeon convinces Jang Uk she is the real Bu-yeon who sees energy, offers her powers, and asks him to come for her before her wedding.
Uncle Yun-o reveals he will wed Jin Bu-yeon, while Bu-yeon clutches a petal and says she is waiting for her groom to take her away.
As the bride arrives at the groom's house and hope fades, Jang Uk appears and Bu-yeon leaves with him, calling him her husband.
Bu-yeon wants to be carried, mistakes his order to shed her heavy robe for something else, then admits she remembers nothing before Jinyowon.
Jang Uk looks for a soul shifter's mark in her eyes, dodges questions about Naksu, then says he only wants her powers to deal with the ice stone.
Bu-yeon sizes up Jang Uk's house, he introduces her to a stunned Maid Kim as his bride-to-be, and tells Bu-yeon to make herself at home.
Lending her old clothes, Maid Kim probes the stranger and is stunned to hear she proposed and that Jang Uk agreed to marry again.
Caught swiping liquor, Bu-yeon insists Jang Uk share a wedding drink to seal their marriage and teases him about their first night.
Jang Uk asks her to snuff a Jinyowon lantern that never goes out; she cannot, admitting she lost her powers with her memory.
As Jinyowon closes in through her tracking thread, Bu-yeon confesses she likes him; Jang Uk severs the thread so she can leave quietly.
Someone tracks a damp, strange energy through the sleeping house to its hiding place and drives it off by feeding it a broken Jinyowon relic.
Maid Kim says Jang Uk sat by her all night and ordered three days of medicine; Bu-yeon learns why wicked things swarm him.
Arriving with medicine, Heo Yun-ok recognizes Jin Bu-yeon from the portraits and tells her the whole capital is searching, Seo Yul included.
Bu-yeon tells Seo Yul he is handsome but her heart went elsewhere last night, learns he was never her groom, and he asks if they have met.
Taken by Jinyowon's people, Bu-yeon asks for three days; recalling why she refused to run, she returns to a tearful embrace from her mother.
Lady Jin says Bu-yeon must be shown as heir but never be seen again, lest anyone learn she has no powers, and reties the tracking thread.
Jang Uk finds his undying lantern dark and recalls Bu-yeon's half-truths, while she is presented as Jinyowon's heir to a startled assembly.
Jang Uk dares Bu-yeon to snuff the lantern, she does, and he declares her his wife; Bu-yeon confirms the wedding drink before everyone.
Uk and Bu-yeon announce their marriage; Lady Jin calls it a lie and the Assembly threatens Uk, who vows to take her anyway.
Asked to prove the marriage, Uk claims Bu-yeon is with child, stunning the Assembly and dodging the physician's check.
Bu-yeon tells her sister her groom has come for her; Dang-gu and Cho-yeon are stunned and the Assembly settles for Uk as son-in-law.
Toying with the relic, Bu-yeon turns the lantern back on and a memory flashes; Uk tells her regaining memories will return her powers.
Bu-yeon frets over the fake pregnancy, admits she hoped Uk came for her, and he offers help only if she drops that hope.
Her mother pulls the thread sewn into her flesh; Bu-yeon endures the pain and begs Maid Kim not to send her back.
As Lady Jin keeps calling her daughter back, Uk confronts her: his wife cannot sleep. By dawn Bu-yeon's pain is gone.
Uk tells Maid Kim to marry; she asks him to throw away the egg and the jade tied to a dead girl. He keeps them to know she is gone.
Meeting Master Heo and Dang-gu, Bu-yeon owns up to the fake pregnancy, sizes up their energy and sniffs out eavesdroppers.
Walking her home, Dang-gu lets slip that Uk broke into Jinyowon to destroy the thread while telling her only to endure.
Bu-yeon finds the towers Uk raises for each soul shifter he kills; one collapses, revealing a stone that stirs a memory.
Bu-yeon catches her tail by sensing energy, holds her breath underwater against the drug, and is helped out by an old friend of Uk's.
Uk's childhood friend gets them lost and insists he is smart; Bu-yeon prefers a handsome fool, then asks about a blue-eyed soul shifter.
At a shady cosmetics shop Bu-yeon senses ominous energy and guilts a royal posing as a eunuch into buying a turtle.
Bu-yeon waits to thank Uk for the thread and a memory of a master's promise and order surfaces.
Young Lady Heo reveals Uk has been staying away at Jeongjingak and hints Bu-yeon is the reason.
Heading to see Uk, Bu-yeon spars with Yun-ok and Sun-i, learns the blue jade is Naksu's and is dared to call him with it.
Uk rushes out when the jade calls; Bu-yeon greets him with a regained memory that the two of them have long liked each other.
Bu-yeon proves she saw the egg-choosing memory, then realizes it belongs to the blue jade's owner; Uk admits he is disappointed.
The stone tower collapses again; Uk presses the jade on Bu-yeon to learn his lost love's last feelings, and she bitterly gives up hope.
Left alone, Bu-yeon curses Uk, dares a tiger to eat her, and is met by a swarm of bugs instead before the search party arrives.
Browsing anti-Naksu charms, Bu-yeon is told Naksu will resent her most, and hears of the small, feisty servant girl the owner once knew.
Bu-yeon scolds the 'eunuch' for abandoning the turtle, confides her husband left her, and he admits he took it home after all.
Bu-yeon is told this is where Uk met and proposed to Naksu, begs to hear no more, and then sees a proposal memory herself.
Walking her home, Yul gets lost again; Bu-yeon senses something strange in his body and he asks her to let it slide as a friend.
The Queen schedules a banquet on Naksu's day; Maid Kim gleefully makes the invited Bu-yeon try on outfit after outfit.
Uk compliments then corrects himself, fusses over her nails, and asks Bu-yeon to show the banquet she is his wife.
Introductions at the banquet; when the Queen moves to send Cho-yeon away, Bu-yeon offers to leave in her place.
Bu-yeon brushes off Yun-ok as fireworks are announced in her honor, but in the back garden she is told the banquet was bait.
Under the fireworks a soul shifter kills 'Bu-yeon', but she walks in alive: it was Gwiseo, Jinyowon's nail-eating white mouse.
The plan with Bu-yeon is revealed; Uk chases down the soul shifter and publicly declares Naksu gone for good.
At the cliff Uk relives his vows to his master Mu-deok and her confession, and admits he could not cry for her.
Uk wakes to find her beside him; she claims credit for chasing off the wraiths so he could sleep, and he lets her stay on her side of a line.
Bu-yeon haggles for a fan and watches a couple brawl over an affair; Uk tracks her down, tells her to say when she is sick, and mocks her bargain.
Uk tells Bu-yeon to look lovestruck while he flaunts her to the Queen, rejects her plea to shift her soul, and warns her never to touch his wife again.
Uk warms the cold water for the Crown Prince's turtle; hearing of it, the Crown Prince spirals into imagining what Uk meant by the gesture.
Bu-yeon thanks Uk and promises to stay by his side, but taking his hand stirs a memory and he accuses her of offering herself as a substitute.
Uk tests holding Maid Kim's hand, gets scolded for upsetting Bu-yeon, and offers a clumsy apology about chickens, pheasants and dogs.
Bu-yeon tells her mother she is regaining her powers and refuses to leave Uk; Lady Jin sees she is in love and demands Uk come apologize.
Bu-yeon rehearses a proud plea through a closed door and counts to three, only to learn she was talking to the wrong man.
Bu-yeon asks Uk to visit her mother and he declines; too late he learns Lady Jin offered to forgive them and Bu-yeon went alone.
Bu-yeon arrives alone with the gifts, then Uk appears behind her and formally apologizes to Lady Jin.
Uk talks Lady Jin into giving them a room; alone, Bu-yeon misreads his intentions before he asks her to open Jinyowon for him.
Sneaking through the garden, Bu-yeon tells Uk how she imagined sitting alone atop a tall tree hoping to be rescued, leaving him shaken.
Uk accuses her of confusing him; she knows of a tall tree he once promised to climb, and insists that it is her hand he is holding.
Bu-yeon senses Yul's energy at Jinyowon; meanwhile a captive So-i names one suspect after another rather than give up her secret.
Uk asks Lady Jin to let him into Jinyowon as Yul and Bu-yeon find the wounded So-i, who tells Bu-yeon she only thinks she is Jin Bu-yeon.
Yul understands Bu-yeon was Naksu all along; overwhelmed, he asks her to let him stay a moment and begs her not to tell Uk.
Bu-yeon insists she came for her friend Seo Yul, not Uk's, and refuses to go home until Uk gives in and walks her back.
Bu-yeon recalls meeting So-i and Yul, says Yul would have been a kind husband, then teases Uk to summon fireflies or fireworks.
Bu-yeon locates the hidden earthenware and explains she sees others' memories by touching their things, then is told she resembles spring.
On the boat Bu-yeon suddenly hangs over the edge, recalling having no strength, and realizes this memory is hers.
Feeding the turtle, Bu-yeon and the Crown Prince, whom she takes for a eunuch, swap marriage advice and confessions of feeling like a fraud.
Showing off her Songrim plaque, Bu-yeon speaks of a harsh master in words that shake Uk, then vows to grow strong and protect him.
Bu-yeon wants to see whether the giant tree she remembers is real, and Yul offers to take her to Danhyanggok.
Uk hunts for the jade, learns she is going to Danhyanggok with Yul, and the two squabble over friendship before he leaves rattled.
At the place where they first met, Yul recalls how much he liked her as a child and his regret at doing nothing.
Cheonbugwan mages beat So-i over the missing parasite while her servant finds Yul on his trip with Bu-yeon and tells him she was taken.
Breaking her promise, Bu-yeon tells Uk that Yul is severely ill and she saw a strange energy inside him.
Bu-yeon apologises to the unconscious Yul, sees a strange memory of Danhyanggok, and clashes with Young Lady Heo over a sealed letter.
Uk tells Bu-yeon to stay out of it; she says Yul is her friend too and she will help until the end.
A warning about pregnancy sends Dang-gu into a panic; Bu-yeon volunteers and flatly insists there is no chance for her and Uk.
Heo Yeom draws Yul's last energy into the wick and places it in Bu-yeon's mouth; she must not open it before time runs out.
At Jinyowon, Go Won meets the shaman he knew and learns she is Jin Bu-yeon, and that Jang Uk is the husband she complained about.
Uk and Go Won use the gold's energy at the fire bird's barrier to pull the parasite from Bu-yeon, then race back to revive Yul.
Bu-yeon says she is going home of her own will; Uk claims he has no use for her, and her parting jab stings.
Uk replays her parting words, finds the lantern she gave him, and remembers her turning off the last lantern.
Yul learns So-i died and the parasite is gone, and apologises to Bu-yeon about Danhyanggok as Master Lee arrives.
Uk finds Bu-yeon at Jeongjingak, explains the ice stone, and admits that when the lantern goes dark he longs for her; she turns it off.
Bu-yeon feels the ice stone's power inside him; Uk admits he no longer wants it gone, and she vows never to grant that wish.
Planning to undo the promise, Uk practises his marriage plea; Bu-yeon lets slip her mother's needles and decides to go home first.
Bu-yeon fusses over Uk before leaving and says she knew he was her husband at first sight, echoing an old memory, while someone watches.
Yul tells of a dream of losing someone he cherished, says she will learn who she really is, and asks her to turn a blind eye.
Watching Uk change, Bu-yeon asks about the sword scar, refuses to visit Danhyanggok, and is moved that he asks her to wait.
At Uk's graveyard Yun-ok splashes a scar-revealing medicine on Bu-yeon; Yul stops her, and Bu-yeon sees the blue marks and asks if she is her.
At the tree, memories of her crazy master flood back and she realises she was Naksu, then the body's true owner speaks to her.
Bu-yeon says she remembers a man she hurt too badly to face; Uk, wounded and jealous, lets her go as she leaves for Jinyowon.
Uk sneaks into her old room, refuses her 'confused' excuse, and vows to be the brazier waiting until she misses him.
When Lady Jin sends for the plaque, Bu-yeon pulls rank on Cho-yeon to go herself, remembering Jin Mu as the man who trained and killed her.
Bu-yeon arrives with the plaque, refuses to surrender it, and offers to prove her returning divine powers to Jin Mu.
Jin Mu throws the plaque into the sorcerers' prison Gwido; despite Ho-gyeong's fear of the wraiths, Bu-yeon promises to bring it back.
Bu-yeon is daunted by the vast prison; after a long silence Uk appears beside her and asks about the marks in her eyes.
Cornered in Gwido, Bu-yeon admits she is a soul shifter whose soul belongs to someone else; Uk hides it and claims the right to stand that close.
The missing turtle turns up and a door to Gwido appears; Bu-yeon later admits she opened it herself and regrets what Uk saw.
Searching for the plaque, Go Won asks for the blue jade back, then admits he wanted Naksu and is ashamed; Bu-yeon tells him to hurt, then let go.
Alone with her, Uk explains why he must not recognize her, wonders aloud about staying together, and answers that it would be wrong despite the longing.
In Gwido, Jin Mu thinks Bu-yeon will help him claim an ice stone, but it drains him instead, and he realises who she really is.
Bu-yeon resolves to stay in Gwido until her soul vanishes so Uk need not slay her; the turtle then brings her the Jinyowon Plaque.
Seo Yul reveals Jin Mu controlled soul shifters, so the massacre was not her will; she refuses to accept it as an excuse.
Bu-yeon reports Jin Mu's fate; the officials realise she could remove Uk's ice stone and vote for it, and she agrees to obey.
Uk leaves to hunt the last soul shifter and finds her; she accuses him of using what is between them, and he says he already let her go.
Uk explains why she waited on the tree, finally carries her, and they tease each other over chestnut rice and a thrown knife.
Refusing to watch one hunt the other, Master Lee announces he will end their current relationship by being witness at their wedding.
After a mix-up over which way to face, Master Lee lists all four of her names; she picks her birth name, and he links light and shadow.
Over the wedding drink, echoes of their past promises play out before Master Lee declares them husband and wife.
Looking out over the world, Uk says he recognized the girl with the blue marks in her eyes from the very start.
Uk refuses to count the days left; she promises a sign when her final memory returns, and Master Lee thinks of Seo Gyeong's unsent letter.
Uk sets the yin-and-yang jade aside; the sign she promised comes back, and her last memory answers how she felt in their final moment.
Bu-yeon wakes the fire bird atop the constellation basin and the seventh star guides it to Uk at Lake Gyeongcheondaeho, where it vanishes.
After the fire bird disappears, a voice returns the shadow to the light that saved the world.
Uk is still carrying his wife up the tree as promised; they bicker about training before going after a huge escaped cat.
