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.
Learning Bu-yeon never came home, Maid Kim snaps that she is not an object to return, and laments Uk's stubbornness.
Uk replays her parting words, finds the lantern she gave him, and remembers her turning off the last lantern.
Haunted by advice and memories of her, Uk watches the lantern blink on and off and tries to talk himself out of going.
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.
Park Jin admits he told Yul to stay out of it; Maid Kim calls him out, and Uk vows to win over Lady Jin.
A palace messenger delivers a chest; inside is the Gold Plaque left for the late king's son, and Go Won reports the turtle gone.
Watching Uk change, Bu-yeon asks about the sword scar, refuses to visit Danhyanggok, and is moved that he asks her to wait.
Go Won confirms Uk holds a Gold Plaque too, and tells him to go north if he will not fight over it; Uk obeys.
Uk tells his elder he is going north and asks if he will back him; he says he knows his target and what he must protect.
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.
At court Uk is named general of North Fortress and asked whether his wife will come; he says she will not.
Uk agonises over who the other man could be and whether he is less than a brazier on a summer day, yet admits he misses her.
Uk sneaks into her old room, refuses her 'confused' excuse, and vows to be the brazier waiting until she misses him.
Maid Kim wants to follow Uk north, Park Jin protests, and Uk tells her to stay with his uncle.
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.
Go Won reveals he never went north and wants to join Uk against Jin Mu, giving the pettiest possible reason: Jin Mu got rid of his turtle.
Uk admits Bu-yeon's heart is with someone who cannot recognize her; Go Won leaps to wild conclusions and mocks Uk's useless power in love.
The missing turtle turns up and a door to Gwido appears; Bu-yeon later admits she opened it herself and regrets what Uk saw.
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.
Uk traps the secret room in a barrier and fights every soul shifter, telling Jin Mu he came to do what is right, not for revenge.
Leaving for North Fortress, Uk tells Maid Kim she is his top priority and asks her to be the prettiest, happiest bride.
Yul delivers the news Uk would rather not hear; Uk explains he turned away knowing he would have to slay her if he acknowledged her.
